Graham Potter has led Chelsea to an undefeated start to his Stamford Bridge career in all competitions. He has also racked up five clean sheets since he joined them in September. The former Brighton & Hove Albion manager took up the reins after former manager Thomas Tuchel was sacked by the club.Chelsea currently sit in fourth place in the Premier League standings, with one point separating them and Manchester United, who sit in fifth. A win for either side will go a long way in ensuring a top-four finish, and both English giants will be expected to give it their all.Ten Hag has been in charge of the Red Devils since the start of the season, when he took a shock loss against Brighton & Hove Albion, then managed by Potter.

If he can secure all three points against Chelsea today, it will mark a second consecutive win against a big English side.
