Manchester United youngsters Adnan Januzaj and Wilfried underlined their claims for first team roles in David Moyes' side with inspired individual performances as the club's Under-21 side sealed their place in the Manchester Senior Cup final with a 4-0 win over Bolton at the County Ground.

The United boss has come under considerable pressure after back to back Premier League losses to arch rivals Manchester City and West Brom but will take heart from the performances of his potent options in reserve, which also included another impressive performance from the returning Will Keane, who netted his fourth goal in three games.

Warren Joyce's side wasted little time after Keane found the back of the net after connecting with a cross supplied by summer signing Guillermo Varela after just two minutes. But after their lethal start, a resilient performance from Bolton's shot stopper Jay Lynch, a former United trainee, saw the score kept at 1-0 for the duration of the first half.

Januzaj, who almost clinched a late equaliser in the senior side's 2-1 loss to West Brom after another promising cameo appearance from the bench, was in rampant mood as the game progressed, tormenting the Bolton defence with his driving runs and intricate link up play.

Zaha meanwhile, who has not featured since the club's Community Shield win over Wigan or even made an appearance for the club's Under-21 ranks prior to Monday's game, was also producing the form that convinced Sir Alex Ferguson to sanction a £15m for the former Crystal Palace youngster last January.

The 20-year-old embarked on marauding run before striking the wood work with an excellent effort, while more diligent goalkeeping denied Keane and Larnell Cole from doubling United's lead.

Tom Thorpe was denied by the cross bar when he got on the end of a Januzaj cross with a splendid diving header, but it would be the young Belgian to add to United's lead with a magnificent individual effort.

Collecting the ball from Cole on the right hand side of the pitch, Januzaj shifted his feet before cutting inside and firing an unstoppable effort in the top right hand corner of the net, an effort that sparked an avalanche of goals.

After arguably being United's most impressive attacking outlets during pre-season alongside Jesse Lingard, Januzaj and Zaha were once again proving to be the difference.

Two minutes after his stunning effort 18-year-old Januzaj found Zaha in the box with pin point cross, which the England international duly dispatched.

Cole, another who may harbour desires of clinching a first team role when United take on Norwich in the fourth round of the Capital One Cup, rounded off proceedings when a terrific tackle from Tom Lawrence freed the England Under-20 international to bear down on goal and strike a composed effort past the well-worked Lynch in the Bolton net.
