Cristiano Ronaldo has already had an emotional season, admitting he was “sad” earlier in the campaign.
CR7 insists he is happier now, and his team-mates at Real Madrid believe he is in the best form of his record-breaking career.
And so Manchester United must be waiting with trepidation for their devastating former star to attack their back-line, during their upcoming Champions League encounters.
One of United’s defenders who will be tasked with keeping Ronaldo quiet is his old friend, Rio Ferdinand.
Veteran stopper RioFerdi5 knows CR7 will be hard to stop, and so he is hoping the Portuguese goal machine has one of his emotional moments.
Ferdinand reckons competing against the team where he made his name will be a tear-jerking experience for Ronaldo, and the United man hopes the Madrid forward’s emotions get the better of him on Wednesday night!
"It's obviously going to be an emotional night for Ronaldo and a great night for him too," Ferdinand said in the Daily Mirror.
"But hopefully it gets too emotional for him.
"We've had a few texts, but when you get into a situation like this when you're coming up against a friend, all the texts and the conversations go to one side and you don't really speak until you actually get the game over and done with.”
But Rio knows that Ronaldo- happy or sad- is not the only factor United need to concentrate on when they take on Real Madrid.
"We're going to have to use all of our experience, courage and ability to make sure that we stop not only Ronaldo, but the other players they have, because Real are a great team,” he said.
"They have so many other weapons. We could shut Ronaldo down for 90 minutes, but they still have players to hurt us, so we have to be compact and work hard."
Meanwhile, United defender Rafael says CR7 is “the best player in the world.”
Having played alongside Ronaldo, Rafael is also aware of the nightmarish challenge he has before him.
"I know what he can do because I played and trained with him a lot," said Rafael.
"So he's not the type of opponent where you would say 'he's good but I don't know what he can do'. I know what he can do.
"If you concentrate, that's the key, reading the game. For me, he's the best player in the world. I think he's the complete player and I really like him. I think he's the number one. I'm sure he'll get a good reception back here [at Old Trafford]. I think it'll be massive."
