Chelsea's key players return from international duty with Sunday's home game against Manchester City on the horizon. Here is the update. Moises Caicedo (Ecuador): South American international fixtures are among the most physically demanding in the global calendar. Caicedo's involvement level and the minutes he accumulated will be assessed carefully by Maresca's medical staff. Caicedo is Chelsea's most important player in terms of the City tactical battle — his fitness is critical. Cole Palmer (England): featured for England during the break. Any additional England minutes increase his sharpness and confidence. Palmer arriving at Sunday's game in peak form is Chelsea's single most important performance factor. Levi Colwill (England): the young centre-back's England appearances continue to build his experience and confidence at the highest level. His international performances have been encouraging. Reece James (England — if involved): any James involvement reduces concerns about his fitness and indicates he is in the physical condition to start at Stamford Bridge against City. Enzo Fernandez (Argentina): South American schedules mean late returns and potential fatigue. Maresca will assess his condition carefully before selecting him for Sunday. All reported fit and returning to Cobham today. 📅 Sun 12 Apr, 07:30 UTC | Stamford Bridge 🏆 GW30 | Chelsea Returns
