Shakhtar Donetsk coach Paulo Fonseca is preparing for one of his toughest challenges as Manchester City visit in the Champions League.
Mourinho confirmed that Zlatan Ibrahimovic, who has not been involved in United's last two matchday squads as he continues his recovery from a long-term cruciate knee ligament injury, has a "big chance" of featuring against City.
One player unlikely to feature for United against City is left-back Luke Shaw, who has been frozen out by Mourinho but produced an enterprising display on his return to the starting XI against CSKA.
Fernandes is a different prospect entirely and it will be interesting to see how many more chances he gets in the weeks ahead. He's injured but he will play for sure.
Manchester City's third successive late victory "shows what we are", manager Pep Guardiola said after David Silva's 83rd-minute winner saw his side equal a Premier League-record 13th successive triumph.
"We started well but lost our patience and couldn't find the players in position".
Pep Guardiola said in his pre-match presser that he wants his team to win this game, but that doesn't mean he'll go with a really strong team.
Shakhtar's motivation was obvious and in Brazilians Taison and Bernard they boasted plenty of attacking drive.
United fell behind late in the first half when Vitinho's shot from Mario Fernandes's cut-back struck team-mate Alan Dzagoev on its way into the net.
For their opponents, a draw would guarantee Shakhtar a place in the round of 16 and even a defeat would be enough for the Ukrainian side provided Napoli don't beat Feyenoord. No stories of (Alexandre) Lacazette, David Silva.
Shakhtar booked their place in the knock-out stages - with boss Paulo Fonseca promising he would carry out his post match media duties wearing a Zorro mask if they got through. "I think that team won't be jumping with happiness to play against us".
