Petr Cech has warned his former club Chelsea about the "difficult" match they have against Manchester United on Thursday night. It comes as both sides are going through indifferent patches of form.
The Blues head into the game in third place, five points clear of Arsenal in fourth and with a game in hand on them too. Their form has been inconsistent though, winning three and losing two of their last five fixtures.
They come up against a United side that are sixth, and six points off the Champions League places having played a game more. Ralf Rangnick's men have only won once in their last five, leading the coach to say their top four chances are unrealistic.
