Chelsea capable of winning title - Mata
The Spanish midfielder is well aware that it will be a difficult season for the Blues following their Champions League/FA Cup double last term but feels that Fernando Torres and new signing Eden Hazard are ready to fire in the absence of the departed Didier Drogba.
"Our main challenge this season is to win the Premier League," he told Sky Sports.
"It won't be easy because the big clubs have reinforced their squads, and I expect a hard campaign.
"Chelsea have worked well in the transfer market and now it is important for the new men to settle quickly.
"We will miss Drogba because he is a legend of the club but now is the moment for Torres and I have total faith in him.
"I also know the work of Hazard and really this man could be one of the positive surprises of the season."
