Manchester United boss Ole Gunnar Solskjaer says that if Brandon Williams and James Garner can play in Belgrade, they can play in the Premier League.
The pair shone in their Europa League win at Partizan Belgrade.
Solskjaer said, You don't get the atmosphere we faced in Belgrade when you play in the Premier League and I think players like Brandon and Jimmy will have grown many centimetres in confidence in those 90 minutes.
If they can perform like they did in front of such an intimidating crowd then they won't have any problems going anywhere in England.
It was as loud and as hostile as it gets but it didn't faze them one bit.
But that's part of the learning curve we are on as a team.
I really believe that we have gained two Premier League players in Belgrade and I won't have any doubts about playing them at Norwich."
