PHOTO: Jose Mourinho writes down Chelsea's biggest problem

Chelsea boss Jose Mourinho believes his Chelsea side lacked something vital during the Blues’ 1-0 loss at Crystal Palace.

In the aftermath of Chelsea’s disappointing 1-0 loss at Crystal Palace, Jose Mourinho adopted a beaten approach by suggesting his side are out of the title-race.

His comments are a little premature, after all, Chelsea still lead the way at the top of the Premier League ahead of Manchester City who drew at Arsenal and Liverpool who face Spurs on Sunday.

Chelsea’s remaining fixtures are kind, but the title race is out of their hands and they will be relying on Manchester City to slip up over the next six weeks.

For Mourinho, it has been a similar story all season as Chelsea’s dropped points against Crystal Palace mirrors those dropped against the likes of Aston Villa, Stoke City and West Ham United.

In the press conference after the game, Mourinho was asked what the underlying problem had been and he responded by writing it down as it had been rather vulgar.

A politer word to put it would be courage, and perhaps being braver in relation to his strikers in front of goal.

It is no secret that Jose Mourinho feels utterly frustrated with his forward’s lack of killer instincts, and it’s a position which desperately needs filling this summer.

Fortunately for the Portuguese boss, Atletico Madrid’s Diego Costa has the quality and courage required and scored yet another vital goal today.

If there is any logical Chelsea signing to be made this summer, the Brazilian goal machine definitely tops the list.
