Former Arsenal midfielder David Bentley has lifted the lid on the worst training ground clash he's seen.

Bentley made one Premier League appearance during the historic Invincible season of 2003/04.

He claims he was often left with a black eye after collisions with the likes of Patrick Vieira or Thierry Henry.

“You don't realise until you're away from it," Bentley told BBC Radio 5 Live.

“Every day training was so intense, it was like a match every day, technically gifted.

“You just slotted in as a young player trying to make your way and fit in. But you'd get smashed every day.

“Vieira would smash me every day, Henry, [Giovanni] Van Bronckhorst.

"You'd go off with black eyes, there would be fights.

“The worst fight I've ever seen, Pascal Cygan and Kolo Toure.

“Trying to get them two off each other was unbelievable.

“It was like 'I'll leave them to it'.

“But that's the intensity and that's the winning mentality.

“And then when you leave and you go to a different club, you think it's not the same."
