Manchester United boss Jose Mourinho has warned his young players he's planning a big summer market.

Mourinho has told his youngsters they will have to be patient for their chance.

He said: “On one side we want the young boys to play. But on the other side we want the young boys to perform.

“And it is difficult for the best teams to win with the young boys' learning curves. This is the reality of things.

“You look, for example, at my last season at Chelsea. Is Ruben Loftus-Cheek playing less than in my last season? Probably less. Is Kurt Zouma playing the same as last season? Definitely less.

“You go to other clubs and you say, 'Young players are playing and being developed', but what are the responsibilities playing for those teams? What do these teams demand from the youngsters? What pressure is there?

“There are contradictions. So if the young player comes and definitely stays in the team for ever, it is because they are ready to perform at the high level, to keep the stability, to cope with the responsibility — and there are not many like this."
