"The lads have been fantastic all season and they've won the league and done wonders again today [on Monday]," he told MUTV. "I think we've thoroughly deserved it on the balance of play and the chances we've created. We had a lot of chances.
"They're a great bunch of lads. There are some absolute pearlers in there, some great players and every one of them, their attitude is absolutely fantastic. They give 110 pe rcent in training every day and in games.
"You could see today they were knackered at the end of the game, but they still kept going to the last minute. The fans have made it a great turnout today and it's nice for the lads as well, for a Reserve game, to play in front of a decent crowd at Old Trafford."
