Ryan Giggs has plans to become Manchester United manager but he admits it may not be a long tenure.

The Red Devils legend is currently assistant to Louis van Gaal, and although he is looking to succeed to the Dutchman, acknowledges that the management caper is a very tough one to prevail in.

"Long term the stats are there," said Giggs.

"It's not particularly about my position - the stats are there. Managers don't last very long in jobs.

"What is it 18 months, two years on average?

"It's a fact - in 20 years' time you won't be in the same job as you are now."
