Hurt hamstring hampers Costa

Jose Mourinho revealed Diego Costa is currently unable to play three games in a week after the Chelsea striker suffered a hamstring injury while on international duty with Spain.

Costa has made a blistering start to his Chelsea career after a $53.1 million move from Atletico Madrid and his impressive haul of seven goals in four games, including a hat-trick against Swansea City on Saturday, has lifted his new team to the top of the Premier League table.

But the Brazil-born star sustained a hamstring problem during Spain's friendly against France this month and was forced to miss its Euro 2016 qualifier against Macedonia as a result.
