Only the most diehard Manchester United fans will remember the name Mads Timm. Once a promising youngster in the Red Devils set up in the early '00s, the Dane never made the grade at Old Trafford and only made one first-team appearance.
But, just because he didn't feature much under Sir Alex Ferguson, it doesn't mean Timm didn't get an insight into how things played out at United during his four years there.
And, in his new autobiography, the former Walsall loanee has lifted the lid on what it was like to train alongside the likes of Cristiano Ronaldo and Gary Neville. Or, more specifically, what the former used to do in training that annoyed the latter.
Describing those sessions during Ronaldo's early career at United in comments relayed by Spanish publication AS, Timm explained how the now Real Madrid star would leave him breathless after training.
"I remember a practice match in training when I was the left wing and he was on the right on the opposing team.
"Every time we crossed, he'd just fly past me. I was hardly ever out of breath after a training session... but that day, he left me gasping."
But, whilst the Portuguese left Timm out of breath, he also had a tendency to leave more experienced members of the United first-team a little exacerbated with his dribbling techniques.
"He would feint 10 to 15 times before dribbling past an opponent and that was something which didn't go down well with players like Gary Neville and Ole Gunnar Solskjær," Timm explained.
You can definitely imagine the disciplined Neville having a few choice words for Ronaldo as he over did it with the tricks.
And those who remember watching the now 31-year-old when he first burst onto the scene in the Premier League, won't be surprised either considering the amount of flicks - many of them unnecessary - he used to try come match day.
With the likes of Roy Keane still around at Old Trafford in those days, it was probably thanks to a few kicks in training that Ronaldo learned to limit his showboating and focus on his other talents.
However, whilst the multi-time Ballon d'Or winner has gone on to huge success since those training sessions, Timm wasn't wholly complimentary about his former teammate's rise to the top.
"He's completely indifferent to the collective side of the game. It was 'Me, Me, Me'. Today, after so much success, he can still get annoyed when one of his teammates scored instead of him.
"Mentally, he reminds me of when I was a 12-year-old. I think he doesn't care what people think of him and that's one of the reasons why he has been able to survive in professional football."
