FC's Stewart Robson analyzes what Ryan Giggs departure from Old Trafford means for his coaching career moving forward.
The talented playmaker has already proved to be a big hit with the Old Trafford faithful and many will be watching closely when he turns out for Mourinho's side. The job Ryan wanted is the job the club chose to give me.
"I want everything", he said.
United are most likely going to sign the fourth player before the start of the season and that would improve their chances of challenging for the Premier League title. "I think it's one of the biggest [clubs in Armenia]". I have to prove not to the others but to myself, that's the nature.
FC's Shaka Hislop discusses how Jose Mourinho will manage all his options next season at Manchester United. I will never be able to work without success.
"I don't hide. I chase Sir Alex's record in Champions League matches". He will be a nine, 10, 9.5, not a six or an eight. "You can tell me his pass is awesome but my pass is fantastic too without pressure".
Mkhitaryan said: "I am very proud to join Manchester United, this move is a dream come true for me".
The Portuguese also addressed the sudden departure of Giggs from the club after 29 years, denying that the decision had been down to him.
United had an initial offer of £18m rejected, but went back in after Mourinho made it clear to executive vice chairman Ed Woodward how desperate he was to sign him.
After the Reds boss let slip in his press conference on Tuesday, the Armenian winger was officially introduced to the world a day later, and said he couldn't be happier.
"We decided four targets". At this time, we were not so successful, so it was not easy for him to adapt. Myself and the structure. "When we have the fourth, I will breathe".
And he takes to his Facebook page to say how privileged he was to play at the Signal Iduna park.
The Scot thinks Mourinho can help lead United back to the top of the English game, following a largely unsuccessful three-year spell since his retirement.
