Terry Pashley urged his Old Trafford heroes not to waste their sensational FA Youth Cup victory at Manchester United.
The battle of last season’s two losing semi-finalists went Burnley’s way as a stunning Jason Gilchrist hat-trick led the way in a 4-3 extra time win.
And after stunning the 10-time winners, Youth coach Pashley was full of praise for his battling underdogs.
He said: “You don’t get much tougher than coming here, and at Old Trafford you are always going to be classed as an underdog.
“We were no different, but this is the cup and we have just caused a bit of an upset and whoever we get now, we can’t waste this result.
“It was a fantastic night and to a man they were fantastic.
“They showed so much composure, quality and a lot of grit and determination because towards the there was a lot of tired bodies out there.
“It got to the stage where it could have been anyone who came off because there was cramp wherever you looked.
“It’s just a fantastic night and a great result.

The Clarets led through Cameron Howieson before United equalised on the stroke of half time.
The hosts led twice in the second half before a Gilchrist brace took the third round tie to extra time
And the Clarets striker, who had already scored three hat-tricks this season, added another to settle the tie nine minutes from time.
Pashley added: “The composure we showed was the most pleasing thing. We came here and got the ball down and played and passed.
“I think we more than matched them in the first half and we knew at half time there would be a bit of a reaction from them They started quite well and as the game goes on we went behind, but Jason does what he does and got another three!
“He has played up there a number of times on his own and we know that if you give him a chance he knows where the net it.
“He has composure and awareness and he gets all types of goals, but the cross from Brad Jackson, who is only 15 by the way, was something else.
“To go past I don’t know how many players and then put the pinpoint cross on Jason’s head was fantastic.
"It just shows again we have some good young players who have had a fantastic experience and it won’t get better than this.
“The manager (Sean Dyche) was here watching and he’s been in the changing room before and after the game.
“He has an important game tomorrow, but he has taken time to stay and watch and I am sure the lads appreciate that. We certainly did as staff.”
