Jose Mourinho demands Chelsea board sign more players to hold off Arsenal and Man United

The Chelsea boss has only welcomed Radamel Falcao and Asmir Begovic to Stamford Bridge this summer.

And while those two are likely to be squad players rather than starters, Mourinho is keen to add at least another left-back following the departure of Filipe Luis to Atletico Madrid.

Baba Rahman is his first choice, but there have also been links with Danny Rose of Tottenham.

"We need a left-back, the board know that and my feeling is that we are going to have one," Mourinho said. 

Chelsea begin their campaign tomorrow at home to Swansea in the late kick off (5.30pm) and are still unsure if Diego Costa will be ready to play.

The Spain striker hit 20 league goals last term as the Blues ran out champions.

And Mourinho says Loic Remy or Falcao will play if he is not available for action.

Mourinho also thinks the league will be tougher than last season.

Chelsea blew away the chasers last term, winning the title by eight points.

"I believe the teams who aren't title contenders will be stronger," he added.

"The gap between the top and others will be shorter."
