Leeds United are expected to be without a key central defender for their visit to Liverpool on New Year’s Day after sustaining an injury in their 1-1 draw at Sunderland.For the second time in a month, Leeds and Liverpool will meet in the Premier League, but Arne Slot will hope his side hold onto a winning margin this time around.There will be a change in personnel and likely formation for Leeds after Joe Rodon suffered an injury in the 1-1 draw at Sunderland on Sunday.The centre-back had played every league minute for Daniel Farke up until he was forced off in the 31st minute, and now he is expected to miss out at Anfield.“Not good,” Farke said when updating on Rodon’s condition after the match. “Joe is my warrior. Has played so many games in a row, and of course he wanted to stay on the pitch. “[He] got a hit on his ankle, and by doing this I think he also rolled his ankle, and it’s pretty swollen.“At the moment, I doubt that he will be available for Liverpool and also for the upcoming games before the FA Cup game. So we have to wait for some further assessment.“But right now, straight after the game, it doesn’t look too good.”Liverpool, on the other hand, did not appear to pick up any issues from their win over Wolves and instead welcomed back Conor Bradley and Cody Gakpo after their respective fitness concerns.Leeds stemmed their run of defeats by switching to a 3-5-2 formation, which has resulted in two wins and three draws from the last five, which includes the 3-3 draw against Liverpool.Rodon is crucial to this set-up, and his withdrawal at Sunderland saw Leeds revert to a back four of Jayden Bogle, Jaka Bijol, Pascal Struijk, and Gabriel Gudmundsson.The switch, however, saw Farke’s side dominate Sunderland in the second half, as they scored, had a total of 11 shots, and created three big chances while keeping Sunderland to zero.This ought to have grabbed the attention of Arne Slot, who has witnessed his side sit off opponents in the second half and invite pressure.In the last four league outings, Liverpool have conceded a combined 30 second-half shots, 11 on target, compared to just three shots on target across the first half.Possible Leeds XI: Perri; Bogle, Bijol, Struijk, Gudmundsson; Ampadu, Aaronson, Stach; Tanaka, Okafor, Calvert-Lewin
