UNITED HORROR SHOW SPURS JANKO

He insisted he has learned from the painful experience and says if he’s given his second consecutive start for Celtic at home to the Championship side then he will be fully prepared.

The raiding right-back said: “You can’t underestimate anyone, you have to give 100 per cent if it’s the Europa League or the Championship, you play at your best.

“Everywhere is like that, you always get Cup-ties where clubs are playing in lower divisions, but it’s the same game. Europa League and Champions League games are the same and we will play our style. We have to be 100 per cent aware and ready for the game.”

Janko started the Capital One cup clash in the MK Stadium last year, but was substituted at half-time when his side were one goal down.

He said: “It was a bit unfortunate. The manager was not happy with the formation and I was the one who had to – not suffer – but go out. At least, I got a few minutes.

“For myself, it was a good experience because not many players play at 18 years old for the first team of Manchester United, so I am very honoured, but it definitely could have gone better if we’d been at it.

“You can’t underestimate anyone. I was one of the younger ones and was trying to give my best, but I think it was difficult for the other players to play with the younger players.”
