Bruno Fernandes expressed his delight at working with a proven winner in Raphael Varane as Manchester United look to challenge for trophies this term.
Varane completed a move to United in a deal worth a reported £42.7million (€50m) in August, following a decade at Real Madrid.
The France international boasts a World Cup medal from 2018, along with three LaLiga titles and four Champions League triumphs to his name from his time in the Spanish capital.
Since his debut against Wolves at the end of August, no player has played more Premier League minutes for the Red Devils than Varane (360) and Fernandes hailed the impact the centre-back could have on Ole Gunnar Solskjaer's side.
"Of course, he’s a winner," Fernandes told United Review. "Everyone knows that. He’s a nice guy and works really hard and is always pushing everyone to do better.
"I think he has a great mentality but, at the same time, we cannot forget the other players. Rapha [Varane] has been brilliant, but Victor [Lindelof] has had an amazing, brilliant beginning to the season.
"Eric [Bailly] comes later because of the Olympic Games, but he’s a player we trust a lot. 'H' [Harry Maguire] we already know is doing really well."
Indeed, Varane led from the front for Madrid last term as well in the absence of Sergio Ramos.
United's new acquisition ranked second for Los Blancos among defenders for duels won (110) and interceptions (36) in LaLiga, while recording 73 aerial successes – more than double the tally of any of his defensive colleagues.
And Fernandes is looking forward for the leadership aspects Varane will bring to United, who currently sit fourth in the top flight after losing to Aston Villa last Saturday.
"Rapha is really important for us, and has been really important for us," he continued. "But the main point is everyone being okay to do the best that they can.
"In football, we all have different qualities, and Rapha has different qualities to Victor, H, Eric and Phil [Jones], but they can all add different things.
"Still he [Varane] is a little bit shy in some ways, because it’s the beginning for him at United, but I think he’s a leader. I think he can help in that part of the game."
