Article: Manchester City say the "sporting integrity" of the Premier League must be protected after a Christmas fixture list that has disadvantaged the Blues and potentially handed Liverpool a helping hand. The two teams are expected to be in the midst of another title slog in late-December, although Jurgen Klopp's side currently hold an eight-point lead over the Premier League champions. Liverpool's challenge could be hit just before Christmas by their participation in the Club World Cup, with games to play in Qatar on December 18 and 21. But the Blues reacted furiously to a fixture change that handicaps them and could help out their biggest rivals. City's game at Wolves has been pushed back from Boxing Day to December 27, kicking off at 7.45pm. That gives them less than 48 hours to prepare for their game at home to Sheffield United, now set for 6pm on December 29. And to compound matters, not only will they have a tighter turnaround than nearly every other club in the league, the fixture change also leaves Wolves short of time to get ready for a trip to Anfield. Liverpool will have had an extra 24 hours of rest ahead of their home game against Nuno's side, who will have to turn themselves round for a 2pm kick-off on December 29. Omar Berrada, Chief Operating Officer of City, told MEN Sport exclusively: “We’re disappointed that the schedule is so tight for the players over Christmas. Premier League games are a huge physical demand, and it’s not ideal to be made to play twice in less than 48 hours because it doesn’t give the players time to properly recover. “We obviously understand that the paying rights-holding broadcasters are an important consideration when it comes to scheduling, but we also need to make sure that we protect the players’ wellbeing, the sporting integrity of the league, and the quality of the product. “We’ve had an open dialogue with the league to consider other options, but ultimately, we will have to comply with the kick off times and dates as they have been presented to us.” While Premier League clubs must comply with whatever time they are told to play at, City bosses did explore other options including pushing the Sheffield United game back but have been left frustrated at how the fixtures have turned out.
