Chelsea failed to bring in a striker in the January transfer window, and that decision could come back to haunt the Blues.Chelsea striker Marc Guiu picked up an injury in the clash with West Ham

Guiu has improved enough to show Maresca that he deserves a place in his first-team squad, helped by six goals being netted in the Conference League. The door has seemingly opened for Christopher Nkunku to earn more opportunities down the centre of Chelsea's attack, at least in the short term.

Chelsea striker Marc Guiu will be sidelined for weeks after picking up an injury during Monday's 2-1 Premier League win over West Ham United, coach Enzo Maresca said on Friday.

“Marc is improving a lot, to be honest. He is doing fantastic; day by day, he is getting more and more ready for that sort of game but sometimes the decision is because I see something and sometimes it is good, sometimes it is not. For sure, Marc, I think day after day, he is more ready,” Maresca said.
