Maresca said after the 2-1 defeat that saw Chelsea exit the FA Cup at the fourth round stage: "I don't think we miss Joao. Joao is happy [at AC Milan] and we are happy Joao is happy there. We had two striker injuries on deadline day, it is something difficult to think. Nico [Jackson] can be back very soon. Sometimes I think you need to play some games without players to realise how important they are. Off the ball, [Jackson’s] pressing is always very good and, on the ball, he is a threat always."
