Juan Mata is today expected to complete his £37 million move to Manchester United after completing a standard medical procedure and agreeing personal terms on his move from Chelsea. The midfielder has endured a difficult time of things recently, having not played in the Premier League since New Year's Day after falling out of favour under Jose Mourinho. The Spain international has had to accept a bit-part role with the Blues in recent months, which was especially damaging for his World Cup hopes this summer. However, his transfer to the Red Devils will boost not only his chances of making Vicente del Bosque's final 23-man squad but also a United side on their knees. The battered Premier League champions are desperately crying out for someone like Mata after dropping out of the FA Cup, League Cup and title race. Their labouring midfield will be rejuvenated, it is hoped, by the Spaniard's arrival, and will be gifted more creativity and fresh attacking impetus. Mata's move comes just as United need him now more than ever and the morale-boosting transfer may buoy disgruntled fans who have seen their side stutter and struggle under Moyes.
