Costa was man of the match - Mourinho

Chelsea manager Jose Mourinho says his side "deserved" their 2-0 victory against London rivals Arsenal, and that striker Diego Costa was "man of the match".

Kurt Zouma and Eden Hazard gave the Blues the win, but Gunners defender Gabriel was sent off seconds before half-time for kicking out at Costa.

It was only Chelsea's second win in the Premier League this season.
