This is how modern social media works…
Juan Mata joins Manchester United from Chelsea, thereby becoming the biggest mover in the January 2014 transfer window, and his new team mates welcome him to Old Trafford on Twitter.
Presumably, Robin van Persie, David De Gea and Rio Ferdinand will all welcome Mata to Manchester United in person, but for now it will have to do online.
As it stands, Juan Mata has not Tweeted since January 20, 2014 and his first Tweet as a Manchester United player is eagerly awaited.
Most intriguing of all, considering David De Gea did not have a fellow Spaniard at Manchester United to bounce around with, is the Tweet from the custodian taking the mickey a little!
