Wolverhampton vs Manchester United match will kick off at 8:55pm Nigerian time.
The match if won will book Manchester United’s place in the semi-finals of the competition.
Under Ole Gunnar Solskjaer, Manchester United have climbed to fifth in the Premier Leagueand knocked PSG out of the Champions League last week.
But Matic expects a difficult encounter with Wolves in the FA Cup and picked out Portugal international Moutinho as a major threat.
United produced a heroic performance against PSG but suffered a disappointing defeat to top four rivals Arsenal just four days later.
‘We didn’t play badly against Arsenal,’ Matic added. ‘We created a lot of chances, we played some good football.
‘But this is the Premier League. Every team has quality and we cannot win all the time.
‘Of course we are not happy with the game that we lost but we know that we did some great things — and Saturday against Wolves is a great opportunity to bounce back.’
