Marcus Rashford sent Manchester United into the Europa League semi-finals after Anderlecht took Jose Mourinho's side to extra-time in a breathless encounter.
Manchester United's English striker Marcus Rashford reacts after missing a chance during the UEFA Europa League quarter-final second leg football match between Manchester United and Anderlecht at Old Trafford in Manchester, north west England, on April 20, 2017.
"Nicky Butt doesn't take him to play that game".
Mourinho was filled with compliments for Rashford - who now has 10 goals in all competitions this season - and Shaw.
Following a hard-fought 1-1 draw in Belgium last week, United required an extra-time victor from Marcus Rashford at Old Trafford to get past Rene Weiler's Purple and Whites 3-2 on aggregate.
Mourinho said after the game that Jones and Smalling - two players recovering from injury - need to show strength and return to action as soon as possible.
Mourinho said Shaw played through the pain barrier, something that the manager was delighted with, and also insisted Rashford's attitude is the reason he has been played so much despite going through a barren period of scoring form before this month.
Asked when the pair were likely to be back in action, Mourinho replied: "If it was me, I think tomorrow".
Players are playing through knocks, and Mourinho also has a real problem at center back with Marcos Rojo also getting injured on Saturday to likely join fellow defenders Phil Jones and Chris Smalling on the sidelines.
We have Daley Blind, who has experience in the position, and I think it is time for Jones and Smalling to be courageous - to risk. He could by age, so when you reach a certain level, and you reach that level for a long time, I don't think it makes sense.
"He can not play every game", Mourinho said after being asked if Rashford was capable of filling in for Ibrahimovic.
"You speak about his qualities and they are fantastic. So instead of coming mid-May you can come the beginning of May, this kind of acceleration of the process".
On Thursday evening, Rashford proved to be United's hero for the second successive game, sealing their place in the Europa League semi-finals.
But there was heartbreak for Socceroos goalkeeper Mat Ryan and Belgian outfit Genk, who could only manage a 1-1 home draw with Celta Vigo and were eliminated 4-3 on aggregate.
