Swansea draw ends tough week for Chelsea - Roberto Di Matteo

Chelsea manager Roberto Di Matteo admitted his team have had a tough week mentally and physically after their 1-1 draw at Swansea.

The Blues missed the chance to return to the top of the Premier League by conceding a late Pablo Hernandez goal.

Although they have played Manchester United twice and accused referee Mark Clattenburg of using offensive racial language, Di Matteo says it is no excuse for Saturday's result.
