“I oversee the programme and I’ve got two coaches, plus four analysts, medical staff and a conditioner for all of the loan players,” he told the Evening Standard.
“We run it seamlessly considering there’s 38 players — everyone gets seen and everyone gets analysis and feedback on their games.
“So you can slander our loan process as much as you want but some of our loan players who are in Germany and Spain are getting looked after better than some clubs who are supposed to look after the players that are right in front of them. I’m very proud of it.
“Sometimes it’s frustrating for the players because everyone wants to play in the first team but only 11 players can get in there.

“Every player is different — some will produce quickly but others take time.”
