Hector Bellerin has explained all the work that goes into making the Arsenal first team.

The rightback, who signed a brand new contract with Arsenal on Monday, explained how he went from Barcelona’s youth squad to the Gunners’ first team in a matter of years.

Similar to Theo Walcott, except a lot earlier in his career, the Spaniard realised how he needed to crack down and although he was still having fun, he was taking his training, not just on the pitch but off it, really seriously.

Everything from lifting weights, to learning about the psychological side of the game, to changing the way he ran came into play.

If it wasn’t for all that, he might not be the player he is today.
