Although the deal has yet to be confirmed by United, a fee has been agreed for Blind and he is expected to be unveiled today.
Writing on his blog, Mata said: “As you read this, many things are happening before the transfer window expires today. Here I would like to welcome Di María and Blind to the club.
“I am sure these two players will give a lot to us and will strengthen the team. We already know what Ángel is capable of, his ability and dribbling skills, and Daley has a great touch and is very intelligent, as he showed during the World Cup.”
Blind will become United’s fifth signing of the summer once a deal has been officially announced and with Radamel Falcao set to join on a season long loan, there is set to be yet more movement at Old Trafford today.
