Topics : Reschedule rebateThe need to cram the remaining 92 games of the season into a five-and-a-half week window also means many more midweek games with evening kick-offs in England, forcing fans in the Far East to tune in during the early hours.Overseas broadcasters will be compensated with a reported £107 million rebate due to the change in scheduling.However, the excitement over the Premier League’s return endures, particularly among the huge number of Liverpool fans, many of whom are awaiting a first league title in their lifetimes.Jurgen Klopp’s men are just two wins away from being crowned champions of England for the first time in 30 years.Hu Zhifei, a 26-year-old journalist and member of Liverpool’s official fan club in Beijing, had planned a trip to see his heroes in action in February that was cancelled due to the coronavirus pandemic.”Nobody is anticipating the league’s restart more than Liverpool fans because we are within two wins of the title,” said Hu, who will tune in to watch the Reds via internet streaming despite kick-offs in the early hours.Excitement is also building in India, where the Premier League has built up a strong following among urban youth in a traditionally cricket-obsessed nation.”Finally I’ll watch some live EPL action. I have already chalked out a schedule for these matches,” Qazi Ahmad Masood, a 17-year-old student, told AFP. “I would love to see my favorite club Liverpool lift the trophy.” That income will be all the more welcome, with uncertainty over when supporters will be allowed back into stadiums and commercial revenues expected to tumble in a global economic crisis.However, without the atmosphere generated by baying fans, the Premier League’s appeal may be diminished in football’s new normal.”What makes it special in England is the way people react to the game,” former Arsenal manager and FIFA’s chief of global football development Arsene Wenger told The Athletic.”It is the best country in the world for the way the fans respond to what’s happening on the pitch. That’s why I think it will be the most handicapped championship without that.” ‘Fast and exciting’ One of the difficulties that lies ahead for the Premier League’s brand will be to maintain the intensity of competition on the field in echoing, empty stadiums.”The Premier League is fast and exciting and no matter whether it is a strong or weak team, the games are great to watch,” said Hu.Fans watching at home will be offered pre-recorded fan noise dubbed over the action to compensate for the real thing.”There is something about the legend that is English football that is all about noise and atmosphere and proximity,” Simon Chadwick, director of Eurasian sport at Emlyon business school in France told AFP.”That spectacle, the product, the noise, the atmosphere, the experience won’t necessarily be there.”However, by overcoming a series of obstacles just to get back playing in the country that is the worst-hit by coronavirus in Europe, the Premier League is confident it will not lose ground in the long run against the Bundesliga, La Liga or Serie A in the battle for viewers across the globe.”We know it won’t be the same without our loyal supporters in stadiums but, together with our broadcast partners, we are able to ensure fans can watch or listen to each match live from home,” said the Premier League’s chief executive Richard Masters. When the 100 day-wait for Premier League football comes to an end on Wednesday, the anticipation will be felt as keenly in Mumbai and Beijing as in Manchester and Birmingham.The global reach of the English top-flight has helped secure its position as the wealthiest league in world football.The Premier League’s overseas television rights deals for the 2019-2022 three-season cycle hit a record £4.2 billion ($5.3 billion) and another £2 billion deal has already been struck for Scandinavian rights between 2022 and 2028.

Milan: Paulo Dybala struck the decisive goal in Juventus’ 1-0 win over AC Milan on Sunday after replacing Cristiano Ronaldo as Juventus stayed top of Serie A, while Lazio and Cagliari moved into the Champions League places. Argentine forward Dybala hit the winner in the 77th minute in the Allianz Stadium having taken the place of Ronaldo 20 minutes earlier. Defending champions Juventus maintain their one-point lead over Antonio Conte’s Inter Milan who had taken pole position after their 2-1 win over Verona on Saturday. AC Milan’s seventh defeat in 12 games saw Stefano Pioli’s side drop to 14th position, just four points above the relegation zone. However Milan had threatened as the former European giants chased their first win against Juventus in Turin in eight years.Wojciech Szczesny was kept busy in the Juventus goal, denying fellow Pole Krzysztof Piatek, Lucas Paqueta and Hakan Calhanoglu. Blaise Matuidi missed Juventus’s best chance before Dybala’s winner when his powerful curling effort flew wide just after the break. Five-time Ballon d’Or winner Ronaldo, who had also been taken off during the midweek Champions League win over Lokomotiv Moscow, reportedly left the stadium before the end of the game after being substituted on 55 minutes. Douglas Costa also came on for Federico Bernardeschi after an hour, with the two substitutions changing the game for the champions. Gonzalo Higuain fed Dybala, who easily shook off Alessio Romagnoli to beat Donnarumma and claim his third league goal this season. “Cristiano should be thanked because he made himself available despite not being in optimal conditions,” said Juventus coach Maurizio Sarri. “In the last month he has had this discomfort in his knee and this a little problem for him. It’s only natural a player is going to be irritated to leave the pitch, especially when he worked so hard to be there.” Returning hero Nainggolan Behind the leaders, Lazio and Cagliari moved into the top four after goal-packed wins. Lazio saw off newly-promoted Lecce 4-2, while surprise package Cagliari continued their superb form with a 5-2 rout of Fiorentina. The two teams are level on 24 points, eight behind Juventus with Lazio ahead of the Sardinians on goal difference. Lazio’s Argentine forward Joaquin Correa hit a brace either side of Sergej Milinkovic-Savic’s strike, with Serie A top-scorer Ciro Immobile slotting in a penalty at the Stadio Olimpico. Cagliari, who battled relegation last season, have been in superb form since Radja Nainggolan returned to the Sardinian outfit after five years away, including a difficult season at Inter Milan last term.The Belgian contributed three assists and capped a stellar performance with the fifth goal of the game on 65 minutes. Fiorentina are struggling without Franck Ribery who is serving a three-match ban for pushing an official. Nainggolan set up Mark Rog for the opener on 17 minutes, with Fabio Pisacane nodding in the second less than ten minutes later. The 31-year-old was involved again in Giovanni Simeone’s third goal against the Argentinian forward’s parent club, as well as Joao Pedro’s effort 10 minutes after the break, before blasting in his second goal of the campaign from distance. He was given a standing ovation when substituted in the 78th minute. “We are doing something extraordinary,” said Nainggolan whose side are unbeaten in 10 games, which include seven victories and three draws. “Nobody would have said at the beginning of the year that we could play so well,” said the Belgian. “There is an enthusiasm that hasn’t been seen at Cagliari for years.” Atalanta lost ground in the league days after their 1-1 draw against Manchester City thanks to a goalless draw at relegation-threatened Sampdoria.Also Read | Paulo Dybala Scores Twice, Juventus Recover To Win Vs Lokomotiv MoscowThe Bergamo side are winless in three league games and played the last 15 minutes in Genoa a man down after Ruslan Malinovskiy was sent off for a second yellow card. Paulo Fonseca’s injury-depleted Roma also showed signs of fatigue after their Europa League defeat in Germany, falling 2-0 at Parma and dropping down to sixth. Parma pulled through thanks to a Mattia Sprocati strike on 68 minutes and Andreas Cornelius finding a way through deep into injury time.
