Jose Mourinho believes Chelsea must learn how to unpick opponents who throw 10 men behind the ball or miss out on the Premier League title again.

The Chelsea manager admits his Stamford Bridge side fell short in last term's Barclays Premier League title race due to a lack of final-third quality.

Mourinho believes new recruits Cesc Fabregas and Diego Costa will help solve that problem, with Chelsea opening their league campaign at Burnley tonight.

"We need more quality in our football," he said.

"When you have matches with space and time it's much easier to play football.

"When you don't have space and time because a lot of football is based around tactics and systems: in a very simple way, everything depends on space and time.

"And when you don't have space and time to play, you need more quality.

"We are working exactly in that direction.

"We have worked on exactly that in training, expecting a team to be defensive and try to close every road to goal."
