Neville, who was speaking on the Stick to Football podcast, brought to you by Sky Bet, said: "I said that I thought he [Trent Alexander-Arnold] had to get more serious about his defending – I’ve said that constantly – or else it will cause him problems. I think it will cause him a problem at Real Madrid because they have Federico Valverde, who is playing right-back currently, and Dani Carvajal when he’s back – he’s going to have some serious competition. They are brilliant players, and he’s going to find it tough there.
"[On whether Valverde and Carvajal are better than Trent] I think Carvajal, from a balance of going forward and back – the problem is that he’s 32 and has had a bad injury – but for me, Carvajal is a better full-back than Trent because of what he gives to the team. It’s unbelievable what Valverde is doing for them at the moment, so he’s going to have competition when he goes.
"Coming back to Trent, I said he needs to get more serious about his defending, and that was proven by the fact he couldn’t get in the England team for many years, and he gets subbed for Liverpool a lot. I’ve never known a right-back get subbed so many times in important periods of matches."
