David Weir has endorsed Bramall Lane hosting next Tuesday's prestigious U21 friendly between England and Scotland.
The United boss is looking forward to the unique occasion and is tipping it to be a good game, with both teams having points to prove to their respective coaches.
On Thursday it was announced George Long would be one of four goalkeepers involved with the Three Lions and Weir has given his blessing for this type of fixture, believing it is beneficial to a young players' development.
Speaking ahead of the clash, the former Scottish international remarked: "It will be a fantastic occasion and I know the Scottish lads will be buzzing about coming down to play in England.
"It is a tremendous opportunity for them to show their abilities; whilst the English lads will all have a point to prove after a disappointing summer.
"Roy (Hodgson) being in charge of the England team emphasises the importance of the game and England will be keen to get a positive result. Billy Stark (the Scotland manager) is a great coach and a top fella; he will be keen to see his group do themselves proud."
"There are many different challenges, staying away from home, playing in unfamiliar surrounds, often against opposition that is relatively unknown. International football at any level is different to club and it is fantastic for the development of young players."
