The Red Devils signed Netherlands midfielder Van de Beek from Ajax over the summer in a deal costing £40million.
Van de Beek, 23, made 175 first-team appearances for Ajax, scoring 41 goals and helping them reach the Champions League semi-finals in 2019.
Despite his influence for Ajax, Van de Beek has made a slow start to his Old Trafford career and is yet to start a Premier League match under Ole Gunnar Solskjaer.
Asked about Manchester United’s summer signing, Fernandes – who has been named captain for the Champions League clash against PSG – said: ‘He’s come from Ajax.
‘I had a coach before from Sporting [Marcel Kaiser], he was Donny’s coach too at Ajax.
‘I know how they want to play and how they like to play – they like that little one-two, that connection and that, if we can say, ‘tiki-taka’ football and Donny is one of those guys from the beautiful Ajax football.
‘They teach that growing up and they give a lot of good players to the world.
‘If you look at the semi-final they played against Tottenham [in 2018/19], most of the players from that team are playing in big clubs and doing well.
‘I hope Donny can do a lot of things for us and I’m sure he will do.
Manchester United face PSG on Tuesday night on the back of Saturday’s emphatic 4-1 victory over Premier League rivals Newcastle.
And Fernandes hopes the win at St James’ Park gives the team confidence as they prepare to face one of the best teams in Europe.
He added: ‘
Of course. When you win your games always the confidence is higher.
I think everyone is confident about having a really good game [on Tuesday]. We know our qualities and we know we will play against one of the best teams in the world.
But we have our qualities and I think we can do a really good game and we need to because we want to start the Champions League in the best way.‘
