Former Manchester United reserve team manager Warren Joyce has lambasted on-loan winger Adnan Januzaj and striker James Wilson for failing to work hard enough to fulfil their potential.

The former Reds academy stalwart, now manager of Wigan, has named the pair - along with former United youngster Federico Macheda - as examples of players who have not fulfilled their potential because of their attitude.

Joyce oversaw the development of scores of junior United players who have gone on to successful careers, from the likes of Jonny Evans and Danny Drinkwater to the recently promoted Marcus Rashford and Jesse Lingard.

But he targeted Januzaj - on loan at Sunderland after to failing to kick on from the progress he made under David Moyes - along with Wilson, loaned to Brighton then Derby and back at the club after suffering a knee injury.

Macheda signed for Serie B club Novara Cacio in December. He went on a succession of loans before United sold him to Cardiff in 2014.

Joyce, who takes his Wigan side to Old Trafford in the FA Cup on Sunday, said: “The frustrating thing is seeing ones like Januzaj, Wilson or Federico Macheda get up to that level and stop doing the work they did to get them to that level.

“Not play the games, not train as hard, sit in jacuzzis and not do the same weights and sessions they did to get there. Those are the frustrating ones for me, because that could be avoided.

“You’re in football for sport, to be competitive and try to do your best and challenge yourself, so those things are on the periphery. You either want to be in a boyband in a pop star environment, or a footballer.”
