Manchester United defender Raphael Varane has praised Cristiano Ronaldo, saying he is an "important" player ahead of their Champions League clash against Atletico Madrid.Varane was a consistent figure alongside Ronaldo at their former club Real Madrid and is well aware of the Portuguese's mindset ahead of big games. The France international believes the five-time Ballon d'Or winner will rise to the occasion against the Spanish giants at Old Trafford on Tuesday.Speaking to United Review ahead of the clash against Atletico Madrid, Varane backed Ronaldo for another big-game performance. He said:“I think he’s a very great player and I think he feels different when the pressure is higher. When it’s a big moment, he can feel – I don’t know if it’s more motivation or something different, but we know in special moments he’s always ready. He will be very important for us.”Varane and Ronaldo played together for Real Madrid from 2014 to 2018. They won four Champions League titles and many other domestic tournaments. The Portuguese striker left Madrid in 2018 to join Juventus. He was reunited with the French defender at Manchester United ahead of the ongoing season.Manchester United@ManUtdThe #UCL stage is set for @Cristiano 🏟️#MUFC | @RaphaelVarane6:28 AM · Mar 15, 20223714288The #UCL stage is set for @Cristiano 🏟️✨#MUFC | @RaphaelVaraneThe five-time Ballon d'Or winner has scored six goals in as many matches for Manchester United in the elite European tournament this season.
