Neymar believes his Paris Saint-Germain team-mates will face a different Manchester United now Jose Mourinho is no longer in charge.
United and PSG face each other in the last 16 of the Champions League with the first leg at Old Trafford on February 20.
The Red Devils will be under the management of Ole Gunnar Solskjaer following his appointment to the caretaker role on Wednesday.
The tie will also be the first competitive meeting between the two clubs.
Neymar said: “We know the quality that Manchester United have and we know that their players have a winning mentality.
“The coach has changed and it will be a different playing style – they’re in the process of changing things up – but we know the quality they have.
“Their will be two great matches between two great sides.
“It is always a pleasure to play in them and I am very happy to be taking on Manchester United.”
United’s defence have the terrifying prospect of facing PSG’s attack of Neymar, Kylian Mbappe and Edinson Cavani.
The Brazilian thinks the French side, who are 10 points clear at the top of Ligue 1, are improving all the time.
“We’re very happy that our link-up play is getting better and better in each match; we’re getting to know each other better as time goes by,” he added.
“And that’s our objective: that everyone be happy to provide assists for the others to score, so that everyone ends the match happy – even though the most important thing is, of course, to win the match.”
