Teddy Sheringham has warned Manchester United they must improve next season to compete with rivals Manchester City.
United finished the Premier League campaign 19 points adrift of champions City in second and failed to win any silverware, losing 1-0 to Chelsea in last weekend's FA Cup final.
Sheringham, who was part of United's famous 1999 treble-winning team, admits the players have underachieved this season.
"Manchester United are all about winning stuff and they haven't done that [this season]," Sheringham told Sky Sports.
"It's very unusual for Jose Mourinho as well because he knows how to win trophies but, they'll have to do better next season.
"There's a lot of Manchester United players that are not playing to their full potential, that's up to them and to the manager to sort that out.
"Man City have taken the game to a different level this year and they will probably be doing it again next season, so they'll have to get a lot better."
