Diego Costa suffers hamstring injuryCosta is expected to be out for at least two weeks
Chelsea manager Jose Mourinho has revealed that Diego Costa has injured his hamstring.
The Brazilian born striker was withdrawn 15 minutes from the end and his replacement Loic Remy scored a late winner.
"It's a hamstring injury [for Diego Costa]," Mourinho said.
"When a striker is playing, the team needs a goal to win the game and he says it's over for him, it's over."
"He tried to play the Champions League final last year with Atletico and was injured, he has that fragility, we know his hamstring is not a strong one."
Costa will have a scan today to reveal the extent of the injury.
