Manchester United midfielder Ryan Tunnicliffe has been warned he must do better.
Tunnicliffe is tipped for big things at United and won praise from Paul Scholes over the weekend.
But coach Warren Joyce told the United Review: "Ryan Tunnicliffe was a little disappointing against West Ham but he's had a couple of good performances since getting into the Peterborough side while Scott Wootton has been in and around the team.
"The reports on both have been very good really."
