Leeds United forward Patrick Bamford has revealed a training ground incident that saw him smack manager Marcelo Bielsa on the head with a football.

Fans and pundits had noticed that Bielsa was wearing crooked glasses in recent weeks, and Bamford admitted that was his fault.

He admits to accidentally hitting his boss on the head while doing a drill during first team training.

"There was one time this season where we were doing a crossing drill. He always positions himself in an awkward place," Bamford said on That Peter Crouch Podcast.

"The ball has come in and I've connected with it so sweetly on my left foot, it's near the top corner. He's stood right inside the goal, I've not seen him, so I've just hit the ball and it has come flush off the bridge of his nose.

"All I saw was his glasses fly 10 metres and him hold his nose. He walked off holding his nose and I was like: 'Sorry, sorry, sorry', obviously sh*tting myself. He's gone a bit angrily: 'It's nothing'.

"I don't know if you've noticed in the last few weeks he's using the same glasses and they're not straight, they're wonky.

"I feel bad, I should really get him a new pair but I'm scared to bring it up again."
