Chelsea are through to the FA Cup final after overcoming Spurs at Wembley yesterday. Manchester City and Arsenal will hope to meet the Blues as they battle it out in this semi-final crunch clash. Stones is out for City while Gabriel Jesus could make an early return. Arsenal have a number of injuries with Ospina, Mustafi and Lucas adding to the season-ending injuries of Reine-Adelaide and Cazorla.
