Manchester United were knocked out of the FA Cup last week.

The Red Devils went into their tie against Championship outfit Middlesbrough as the heavy favourites.

But, despite taking an early lead, they exited the competition after losing on penalties.

Cristiano Ronaldo had one of the worst games of his United career against Middlesbrough.

He missed a golden opportunity to score from the penalty spot in the first-half. Ronaldo looked confident but dragged his effort wide.

Ronaldo tried desperately to atone for his error but nothing was coming off for the Portuguese forward.

A week after their exit from the competition, the FA Cup have now posted a video of Ronaldo's highlights from the game.

They decided to compile all of his 'key involvements' from his time on the pitch. And that included his missed penalty in normal time. View the video below...

The FA Cup also included Ronaldo missing numerous chances, as well as when he got a back-heel horribly wrong and it went out of play.

The video does not look very good on Ronaldo at all. In all honesty, it looks like a 'fail compilation'.

And for that reason their video has gone viral. View some of the reaction below...

Ronaldo has now gone five games without finding the back of the net.

In United's most recent game against Burnley, which ended 1-1, Ralf Rangnick even decided to start Ronaldo on the bench.

The Portuguese's goal-scoring record since joining the club in the summer isn't bad - he's notched 14 goals in 25 games - but still his return to the club has not gone as planned.

Ronaldo will be looking to get back on track in United's next game, which takes place on Saturday afternoon when United welcome Southampton to Old Trafford for their Premier League clash.
