David Beckham stunned Arsenal squad with 'unbelievable' training moment during forgotten spell at the club

David Beckham stunned Arsenal stars with an 'unbelievable' training moment during his short spell at the club.

Beckham is undoubtedly one of the greatest footballers of all time, his obvious talent backed up by the fact that he played for some of the best teams on the planet, including Manchester United and Real Madrid.

The England star's quality was obvious long before he spent a few weeks training with Arsenal in January 2008.

Beckham spent three weeks with Arsene Wenger's squad in a bid to keep fit before returning to pre-season training with LA Galaxy.

Despite being one of the most famous men on the planet, the Arsenal players were still left stunned by what Beckham could do in training.

Speaking on talkSPORT, former Gunners defender Phillipe Senderos was asked to name the best trainer out of four standout former teammates: Thierry Henry, Ronaldinho, Beckham and Kaka.

"Obviously they were all world-class and top," the former Switzerland international began.

"But the best player in training - they all had great quality - but David Beckham for me was unbelievable in training.

"His application, what he would do every single day to prepare himself and be one of the best performers at the weekend, David Beckham."

Senderos then described a moment that left himself and teammate Gael Clichy in awe.

"I remember him once coming to Arsenal to do like a pre-season, we were doing long balls with [Gael] Clichy.

"There was a triangle, Clichy, myself and David Beckham, we were practicing long balls, right foot, left foot, 30/40-yard balls for half an hour.

"He did not miss one ball, every single one would just get right to your foot, one metre from the floor, like really perfect balls. "When he missed the first one, we both stopped and said, 'Okay, that's it!'"

Following his training spell at Arsenal, Beckham returned to LA Galaxy before joining AC Milan on loan in January 2009 and then again in 2010.

In 2013 he joined Paris Saint-Germain before retiring.
