Diego Costa appeared to allay concerns over his fitness by training with Chelsea on Thursday.
The striker was pictured on Chelsea TV making his way out to training as Guus Hiddink prepared his squad for Sunday's FA Cup fourth-round tie at MK Dons.
Costa scored the decisive goal before withdrawing from last Sunday's Premier League win at Arsenal with a knee problem.
The club television channel also reported that Ramires bade his farewells to his team-mates at Chelsea's Surrey training base on Thursday after his move to Chinese Super League side Jiangsu Suning for a fee reported to be in excess of £20million.
Meanwhile, New York Red Bulls defender Matt Miazga was undergoing a medical with the Premier League champions, according to Sky Sports News.
