It now reads:
Mata seems to be a pretty prolific tweeter, in English and in Spanish, although in such a way that it's difficult to tell whether or not the account is run by him or his representatives. Hopefully he might have something interesting to say than the usual 'good to get the three points/we were robbed' but I wouldn't get too excited.
Whether we'll get an announcement on this or not tonight remains to be seen. Whether or not we'll get an announcement on something else seems very likely - there's more Manchester United transfer news ready to drop later, so stay tuned.
