#3 Thiago Silva | Chelsea
Eyebrows were raised when Chelsea signed Brazilian veteran Thiago Silva at the age of 35, but he proved to be a fantastic addition to the Blues' struggling defence. Matters were made even better by Tuchel's arrival as the German has worked with Silva in the past and instilled the former Paris Saint-Germain captain at the heart of his near-unbreachable defensive unit.
Silva started for Chelsea in their previous game against Arsenal, which saw them run ragged and lose 3-1 to Arsenal's youthful side. The loss at the Emirates was one of only three instances that saw Chelsea concede three goals in a Premier League game with Silva in the starting XI. He could possibly look to make amends for a poor display against them last time out and help his side keep a clean sheet.
#2 Willian | Arsenal
After playing week in week out for the best part of nearly a decade for Chelsea, Willian became the latest addition to the list of players who crossed the city divide to join their rivals, Arsenal. The Brazilian winger registered two assists on his league debut for the Gunners but managed just three assists in the following 24 (!) games and has had a miserable campaign for Arteta's side.
The 32-year-old will return to West London to face his former club at Stamford Bridge on Wednesday, and could have a point to prove against the club that allowed him to leave on a free transfer.
Willian scored his first-ever league goal for Arsenal on Sunday with a delightful free-kick and could look to end his season in good form, possibly with a goal against Tuchel's Blues.
#1 Mason Mount | Chelsea
Regardless of the managers in charge, systems deployed, or the positions he's played in, Mason Mount has continued to deliver time and time again for his boyhood club. Mount has featured regularly since breaking into the senior side last season and has gone on to establish himself as one of the best young players in the world, let alone in the Premier League.
The 22-year-old star was deservedly given some time to rest after his heroics against Real Madrid in the UEFA Champions League semi-final as he did not feature against Manchester City at the weekend.
Mount is expected to return to the lineup on Wednesday and will look to continue his fantastic season so far with a great display against Arsenal after being bested by them last December.
