"They need to play," said Carver. "They have gone past under-21 football, the Under-21s is for good young players who are 16, 17 or 18 and a chance to develop.
"The guys who have gone up there and past that are ready for senior football.
"It's a great situation for both parties.
"First of all they are getting some good players.
"Secondly we are getting our young players some experience playing in front of 35,000 to 40,000 every other week, under pressure because we know how big that club is - it's a worldwide club."
