A video of Cristiano Ronaldo humiliating a Sheffield United defender for Manchester United in 2007 is going viral.The clip captioned "No one has ever destroyed a player like this" shows Ronaldo running at poor Chris Armstrong at Old Trafford during a 2-0 victory in the 2006/07 campaign.Ronaldo goes to the right, then to the left, then to the right, then to the left and then to the right again. All the while, Armstrong has to keep twisting and turning to keep his eye on the Portuguese superstar. However, Ronaldo's final dart to the right is just far too much for Armstong to take as he stumbles face-first into the ground.Ronaldo is away and Armstrong is embarrassed.The entire Old Trafford crowd going 'WHEEEEYYYY' certainly wouldn't have helped Armstrong.United's No.7 then has an effort on goal from 25 yards but it's parried by Paddy Kenny in the Sheffield United goal.What a goal it would have been but, still, the skill alone is good enough for it to go viral more than 15 years later.

Even to this day, United fans can't get enough of Ronaldo's skill. Check out the best reaction:

Fast forward to the modern day and it's unlikely we'll be seeing Ronaldo produce this kind of magic in a United shirt anytime soon.

He was left out of the club's 2-1 victory over Liverpool on Monday, coming on for the final four minutes.

Following a brilliant team performance from Erik ten Hag's side, it would be a surprise to see Ronaldo on the teamsheet for their trip to Southampton on Saturday lunchtime.

However, any suggestions that Ronaldo doesn't fit into this United side were quickly dismissed by Ten Hag following their victory over Liverpool.

"I think he can," Ten Hag answered when asked if Ronaldo still fits into United's style.

"In his whole career, he, under several managers, he did in several styles and systems," Ten Hag added.

"He always performed, so, why he can't do this? For me, his age is not an issue. If you are young, you are good enough, and when you are old and you still deliver the performance, you are also good enough."
