Wednesday night sees the Champions League Round of 16 first leg between the two clubs and Ronaldo is the man to stop according to former Old Trafford teammate Evans.
"I am sure one or two of the lads have kept in contact with Cristiano and Nani was obviously on international duty with him," said Evans.
"He will be looking forward to the game just as much as we are.
"He has adapted his game from when he was at United.
"When he was playing here he was a right or left winger and was expected to work back a lot.
"Real Madrid don't play like that, so he has changed his game to suit them.
"There are so many other players who can cause us problems but he will be the one everyone will be looking to as the man to stop and we have to make sure we keep him quiet."
