In the aftermath of United's victory over CSKA Moscow, Jose Mourinho has branded Liverpool as "Luckier" than the Red Devils as Klopp's men have an extra day to prepare themselves for the upcoming Premier League showdown.
United's triumph in Moscow also saw Romelu Lukaku continue his impressive goalscoring form since moving to Old Trafford in a £75million switch from Everton this summer.
Should Lukaku play in both qualifiers, as well as United's weekend meeting with Crystal Palace, it will mean he will have played 14 top-level games within the opening two months of the season - a hefty workload in the modern game, especially for an attacking player.
The Belgian global striker has been an inspiration for both club and country so far this season, scoring 14 goals in 11 games for United and Belgium.
"Of course everyone knows that Jose Mourinho is very demanding and what he said was right", the Armenia worldwide said.
"My solution is you prepare players mentally to cope with the physical disadvantage or because I have a squad with other options, I change players and try to play players that didn't play in the last match".
"He's not a natural footballer and has to work at his game but he's obviously working very hard". The Italian has his own vision of how Chelsea should play and Morata was the man he wanted.
We all know about Lukaku's attributes, but I wonder if it will have surprised even José Mourinho how much he has improved Martial. I think every step in his career he has got it, he has grabbed it with both hands since his first loan to West Brom.
Manchester United after years of struggling are once again the force to be reckoned with in the Premier League and the whole of Europe.
And Keane says United can beat City to the Premier League title as well as going far in the Champions League.
"Over the last few years, you are thinking they might win a League Cup and the lesser trophies".
