It has been a roller-coaster journey for Shaw since his mega-money move from Southampton back in the summer of 2014, a roller-coaster which has a lot more dips than climbs as the full-back has struggled to find fitness and form since hishorrific leg break back in 2015.
"I am not the luckiest guy with draws so it's better I shut up and forget it because we only play in February and until then I have to concentrate on the English competitions", added the Red Devils manager.
The England worldwide has been largely out-of-favour since Mourinho took over the reins at Old Trafford from ex-Barcelona manager Louis van Gaal in May 2016. Tuesday night was just a glimpse of what Shaw can do.
Former Manchester United midfielder Scholes believes Shaw should be starting in the Red Devils team. However, it is clear he is not the long-term answer in the position for Mourinho.
And it's safe to say Manchester United fans were thrilled for him.

"We had Wayne Rooney, who was a player who if he missed a couple of games, you knew, didn't you, he's not looking after himself right, he needs to be playing all the time, Saturday-Monday, Saturday-Tuesday, whatever it may be".
United turned the game around with two goals in two minutes from Romelu Lukaku and Marcus Rashford in the second half to progress to the last 16 as Group A winners.
Shaw has found opportunities very hard to come by at United under Mourinho, who has publicly criticised the defender previously.
"Especially with the ball going forward, really risky, creating a lot, great intensity in his game, no surprise in minute 80 he is feeling the consequences of that intensity, is normal, first match of the season for him".
"Shaw had waited for a long time, it is not easy to give an opportunity to a player in matches when we need results".
Luke Shaw is playing mad.
