Mourinho blames Del Bosque for Costa injury woe

Jose Mourinho thinks Spain coach Vicente del Bosque is to blame for Diego Costa's recent injury troubles.

Costa began the season in prolific form, scoring nine goals in seven matches, but he has missed Chelsea's last three fixtures because of a persistent hamstring injury and he will be absent from the squad for tonight's Capital One Cup tie against Shrewsbury (Live Sky Sports 1, KO 7.45).

The former Atletico Madrid man had also been suffering from a virus in the build-up to Sunday's Premier League match against Manchester United, but Mourinho revealed it was injury, rather than illness that ruled the £32million signing out of the 1-1 draw at Old Trafford.

The striker has been troubled by the hamstring problem for some time, but Mourinho believes it was exacerbated by Del Bosque when he fielded the 26-year-old in back-to-back games against Slovakia and Luxembourg earlier this month.

The Chelsea manager said: "He (Costa) had to go to the hospital and obviously it doesn't help him to recover from his injury. But he didn't play on Sunday because of the injury, not because of the virus.

"Diego has the hamstring (problem) because he played two matches in three days when he was not with us."

Mourinho voiced his concern over a lack of communication with Del Bosque and other national coaches earlier this month and the problem still clearly concerns him.

When asked whether he hoped Costa's injury problems would soon be over, Mourinho replied: "But he still has the national team in November!"

This weekend Mourinho looks as though he will be able to recall the Premier League's deadliest striker.

"I think so," replied the Portuguese when asked if Costa would be fit for Saturday's Premier League game against QPR.

Costa's physical presence would have helped the Blues at Old Trafford, where Mourinho and captain John Terry felt Chelsea should have had a penalty in the first half after Branislav Ivanovic went down in the box during a tussle with Chris Smalling.
