Manchester United boss Ole Gunnar Solskjaer has put his kids on notice for the new season.
Mason Greenwood, James Garner, Tahith Chong and Angel Gomes have all featured in United's pre-season fixtures so far.
Asked whether he has been impressed by the quartet during the tour, Solskjaer told the United app: “They have impressed me before in training over the last six months so that is why they are here.
“It is just a matter of seeing them against good teams with the first-team players. We know they are talented.
“I have no doubt that we will see loads of them his year and in the years to come."
Solskjaer also praised United's new signings Daniel James and Aaron Wan-Bissaka, both of whom have looked bright in pre-season.
"It is always daunting, the first couple of weeks with a new team," the Norwegian said. "But then you stamp your authority, show what you are about and I think both of them have done."
