Manchester United midfielder Juan Mata believes the club must challenge for the Premier League title this season after two disappointing campaigns.Since Sir Alex Ferguson’s departure, the Red Devils have finished seventh and fourth in the English top-flight, well below the usual expectation of the side.And Mata believes the Old Trafford faithful deserve to see the side battling for top spot, as well as winning a trophy.“Last season the important thing was to get into the Champions League,” he said.“Now we need to do one more step forward and try to fight for the title because it is what this club means, fighting for and winning trophies.“This season we want to win an important trophy. We feel it is what the fans deserve.” Juan Mata 1
