The 25-year-old has put pen to paper after a prolonged delay and has become our record signing, eclipsing the £30.75 million we spent on Dimitar Berbatov.
David Moyes has confirmed that Mata is nearing full fitness and may be in the squad to face Cardiff on Tuesday and speaking in his first interview as a United player, Mata admitted he was very excited to start his journey at Old Trafford.
He said: “Today is a very happy day for me, meeting the manager and the team mates. It is a massive and amazing club and I am happy to be here.
“It’s a team that have won the Premier League a lot and it is amazing knowing that a club like United are interested in you.
“De Gea was texting me for the last five/six days asking if I was landing by helicopter or bicycle. He was important for me arriving here.”
“I’m confident that everything will be OK and I will try my best. Everything will be alright because the players, manager and fans are good and everything will be a success.
“It’s a bit surprising to move to United but I am very grateful to Chelsea and the people who work at the club and fans. They voted me the best player and they have been amazing with me.
“The last 6 months have been difficult and I understand it is a team sport and I understanded that situation. Now, with this position, the chance to come to United was a great moment for my career and it is a massive club.”
Mata is already speaking like a United player and he hasn’t even been here for five minutes.
There may have been a huge buzz around the signing of Robin van Persie but potentially, Mata’s arrival has eclipsed that. What a signing he is by Moyes.
We may get to see him in action against Cardiff on Tuesday but if we don’t, it won’t be too long before Mata is on the pitch as a United player.
