Fernandes was the man who took his place in the second half and proved to be decisive as he scored a free-kick late on to help United progress.
Ole Gunnar Solskjaer had admitted on the eve of the game that van de Beek was growing frustrated with his role at United and Fernandes admits he sympathises with the Holland star’s situation.
‘Donny had a great game,’ he told MUTV after the match. ‘Playing in the position I play, watching him he moves really good and played really well.
‘It’s important for us. If I was in the position of Donny I would not be happy at all but the most important is doing what he does today, coming in and helping the team.
‘We have a really good squad and we have options. If you look at the bench and the first XI today and the ones at home we have a really good squad.

‘It will not be a problem if we change the team or someone is tired because we have really good players.’

His winner on Sunday set up a fifth-round tie against West Ham, and Fernandes is determined to win silverware this season with United, who are also currently top of the Premier League table.
He added: ‘They’re all important competitions for us,’ he said. ‘We have to go in the same way whatever the competition.
‘We play in them all to win. Everyone knows winning the league is more special but for us players, it’s about winning trophies regardless and this is a trophy we want to win.’
