Jose Mourinho says injury to Chelsea striker Diego Costa did him good

Diego Costa scored the winning goal for Chelsea against Liverpool this afternoon.

Chelsea have beaten Liverpool 2-1 at Anfield, with their star striker Diego Costa once again the hero. He smashed home a half-volley after Simon Mignolet had parried a Cesar Azpilicueta cross into his path to win the game for Chelsea.

It was his 10th goal in 12 appearances for the club, all of them coming in the Premier League.

It came after some recent problems for the Spanish international. He has been suffering with a long-term groin and hamstring problem, which was exacerbated on international duty for Spain. He also came back with a serious virus from duties with his adopted nation - which saw him hospitalised.

But he certainly looked on it today, with a typically robust and in your face attitude against Martin Skrtel - his recent nemesis in an international game between Slovakia and Spain.

This week Vicente Del Bosque left Costa out of the most recent Spain squad, to allow some recovery time, despite Jose Mourinho not asking him to do so.

And the Chelsea boss believes his most recent rest, as well as the upcoming time off he will get in the next international period, has and will do him good for the rest of the season:

"He is back. Maybe the injury was good because it made him stop, and when he has to stop he had time to recover step by step. In this moment he is in good condition and Spain made a fantastic decision for them and for us. Now he has 15 days to be at the top of his game and when Spain needs him they will have a good Diego, not a bad Diego."

Chelsea fans will hope that Costa is indeed back at his best, because he could certainly fire them to the Premier League title.
