An amazing crowd of over 70,000 helped Carrick’s charity foundation raise over £1million as United’s 2008 line-up drew 2-2 with an All-Star team.

However, Giggs believes that, in contrast, the 35-year-old Carrick still has a key role to play at Old Trafford.

“Everyone deserves a break now because especially in the last week with moving the kick off time and a lot of changes having to be made it was quite a stressful week but in the end we have made it.

“It was a success and better than I could have hoped for. I am delighted.
“I can switch off now. I can totally switch off now when I go away with the family.
“I will probably throw my phone in the sea so I don’t have to answer any more calls or emails and just get my head together again and be ready again to be back for pre-season and do it all over again.”
The United 2008 side twice came back from a goal down to clinch a draw. Nemanja Vidic’s first half header cancelled out Gaizka Mendieta’s opener before Carrick’s 82nd minute blast levelled Robbie Keane’s second goal for the All-Stars.
