After the hefty dispatch of Premier League leaders Chelsea, Jose Mourinho resumed his carrot and stick approach to coaching, unleashing the latter on his pet hate, strikers with attitude, or rather the wrong attitude as he sees it.
"So far has been okay for me but I still have to show I can give more", he told United Review.
Wayne Rooney could return to the Manchester United squad for Thursday's Europa League quarter-final second leg against Anderlecht at Old Trafford.
"We know we are playing a very high level team in Manchester United. Yes, I think. Do I think he can play successfully for me?", Mourinho explained.
United are hoping to reach the Europa League final on 24 May at Stockholm's Friends Arena - where Ibrahimovic is having a statue erected in his honour.
"We saw in the first leg what they can do and we know it is going to be very hard, and we know that pretty much everyone in our team is going to have to put in a flawless performance". I can not say every match is for one or another.
"First of all, if you don't concede, you go through, and that's important for us to know", he said. "Well of course we have to believe and we do believe [we can win] but at the same time we have to be realistic", said Weiler, when speaking at his pre-match press conference inside Old Trafford's Europa Suite on Wednesday evening.
It has been shown a few times this season that players that are out of form or favour with Mourinho can make a return to the side in a big way, but the manager admitted that Martial is going need to do a lot more.
Romero may be in goal against Anderlecht, but Mourinho says that might not be the case if United progress from the last eight.
Tomasz Radzinski scored in Anderlecht's victory over Manchester United in 2000. Now his former club has joined a race of other Premier League hopefuls ready to try to capture his signature.
"But I have always said that I want to play as much as possible. I am happy and I think it is the right attitude", he explained. We lost players in the January market when we didn't bring in anyone and we lost players [to injury] in the global week. The players should know me much better now.
"If we need a goal, he can help us".
"David's priority to play Premier League but I don't like the complete separation".
