With Didier Drogba out for a "couple of weeks" after suffering from ankle issues the blues boss has revealed his intention to gamble on his star Spaniard, Diego Costa's fitness in Tuesday night's champions league clash with Sporting Lisbon.
Costa has been suffering from a tight hamstring over the past month which has caused Mourinho to place a limit of a single game a week on the striker.
However, with tensions rising due to a Drogba's injury and the pressure due to Chelsea only taking a point away from the home game against Schalke, Mourinho feels playing Costa is a risk worth taking.
"There is a risk, yes, but he plays," he said. "We assume the risk and he plays."
Mourinho then went on to say that he wished for Costa to even play at the weekends London Derby game against Arsenal:
"Hopefully everything goes well and hopefully from Tuesday to Sunday he has enough period of time to be back on track and play against Arsenal."
This rather defiant statement of belief in Costa's physical integrity comes after the boss claimed Costa was 'hardly training'.
Whilst this is a great source of excitement for Chelsea fans as they await witnessing their star performer play tomorrow but it may also indicate a sense of nervousness with Mourinho.
Last season in particular Mourinho was certainly not a man of risk taking and to so strongly state his intentions of contradicting his judgement of only letting Diego from starting weekly indicates a little worry in the managers mind.
Perhaps this statement is part and parcel of Mourinho's hunger for winning and thirst for footballing domination but some may interpret this gamble as showing a little lack of faith in the rest of his side's goal scoring potential.
