David Weir has confirmed he has instructed George Long to take 'a couple of weeks off' following the goalkeeper's participation in the U20 World Cup last month.
The United stopper didn't play in England's three unsuccessful group games, but the Gaffer believes his excursions in Turkey, together with a first full season of first-team action at Bramall Lane last term means he needs the added rest.
Speaking ahead of Saturday's friendly against Cowdenbeath, Weir commented: "George (Long) needs a break and chance to get a holiday.
"Given where he has been in the last few weeks and the work he will have done, coupled with the exposure of last season I feel it is right to give him a couple of weeks off.
"I spoke to him before and after the tournament and although he wasn't too keen to have the time off I thought it was crucial given his age and in particular the intensity of his work in the last year.
"He needs to step back and have a break and when he returns he will be eager to get back to work.
"Despite the poor results for England, the whole experience of being in the squad will benefit him massively in the future."
