Henrikh Mkhitaryan says Jose Mourinho's "PlayStation football'' criticism will be at the back of Manchester United's mind when they take the field against CKSA Moscow.
The United boss admonished his side after the 3-0 win over Basel earlier this month in their opening Champions League match, claiming they stopped being professional having gone 2-0 up early in the second half.
Mkhitaryan said those words left a mental imprint on the players, who will ensure there is no repeat performance in the Russian capital as United try to give themselves a three-point cushion in Group A ahead of next month's trip to Benfica.
"Of course everyone knows that Jose Mourinho is very demanding and what he said was right,'' the Armenia international said.
"He didn't exactly say names but everyone thinks they have done something bad or made a mistake.
"We are trying to improve that aspect and stay more focused during the whole game and not be doing fantasy football or PlayStation, as he said, in the last 25 minutes.''
Mkhitaryan added that United, who won the Europa League last season, are among the contenders to win this season's Champions League and said he is feeling comfortable at the club after a period of adjustment during his first campaign.
