Harry Maguire says Raphael Varane will be experience to Manchester United's centre-back stocks.
The Frenchman's transfer from Real Madrid was completed on Saturday and he was unveiled on the Old Trafford pitch ahead of United's first game of the season against Leeds.
"To bring players into this club, obviously of his calibre as well, it's going to be really, really exciting," said Maguire after the 5-1 win over Leeds.
"Everyone in the squad is obviously looking forward to working with him. I think one thing that it does is it boosts our defensive options.
"We've got an amazing number of centre-backs now at this club, all international players who are all proven in the Premier League. You've seen again how well Victor played [against Leeds]."
