The Spanish international had to settle for a place on the Chelsea bench since Jose Mourinho arrived during the summer and David Moyes pounced on the opportunity to bring him to Old Trafford.
Not a huge miss to a strong Chelsea squad with great depth, however, some blues fans are absolutely gutted to see him go, so they made a song to say goodbye.

The song which is performed to the tune of Boyzone’s ‘No Matter What’, was published on YouTube ahead of Mata’s United debut in their 2-0 win over Cardiff last night.
It clearly had no effect on the midfielder who set up the second goal in a composed debut which was sure to delight United fans.
