Juan Mata is usually known as a cheeky little chappy, whether it's visiting the Whitworth Gallery, or checking out local cafes and restaurants with team-mate David de Gea.
The best thing about his upbeat demeanour is that he usually blogs about his life - and not just on the football pitch either, no no no. The Spaniard lets his fans know what he's been up to and who he's been with, and is generally a ray of sunshine for everyone he encounters.

The usually merry Mata is of course keeping his counsel because of the Red Devils' malaise under boss Louis van Gaal, who could well be sacked if he doesn't get a result against Chelsea this evening.
The Dutchman has overseen victories in just three of his side's last 14 games which has piled on the pressure - and left them down in sixth place, three points adrift of Tottenham in the fourth and final Champions League qualification spot.
Reports this morning go as far as to suggest that Van Gaal could walk even if he does guide Manchester United to a win today. For the sake of Mata's sanity, let's hope that's the case.
