At £37mil he is cheaper than what Arsenal paid for Özil and if he can galvanize the team and inspire them back to sharpness and form, then it will be all worthwhile.
Formation-wise, everyone's been talking about a 4-2-3-1 formation where he plays with Januzaj and Rooney in support of RVP. Totally delicious.
Now all we STILL is a good and proper DM. At least we have Fletcher back and he's really been like a new signing.
Hopefully Mata is a total success with us!
