Chelsea manager Jose Mourinho has revealed that he is wary of Sunday's visit to Derby County due to the lack of pressure on Steve McClaren's men to win.

The Rams host the Premier League outfit at the iPro Stadium hoping to record an FA Cup 'giant killing', with McClaren's charges having won eight of their previous 10 Championship fixtures.

Consequently, the Portuguese feels obliged to field his "best possible team" out of respect for the East Midlands outfit, who can perform "without any kind of pressure".

He told Chelsea TV: "He (McClaren) knows the football that can take him not just to the Premier League, but also to play with a certain stability if, or when, they reach the Premier League.

"A team that will play the best they can, without any kind of pressure.

"Do we lose? Do we win? Who knows? At least the message is we respect them and we go there with the best possible team."

Tomorrow's encounter is scheduled to kick off at 2:15 pm.
