Speaking to Genting Casino, Johnson said: "If I had to pick a contract to renew as a priority in the cases of Trent Alexander-Arnold, Mo Salah and Virgil van Dijk, then Trent is who I’d go for, mainly because of his age. They're all world class players, but Trent is the younger man, and he could feasibly be playing in the Liverpool first team for another six, seven years.
"Mo and Virgil, as good as they are, aren’t going to be able to do that. Of course, there are rumours about Real Madrid wanting to sign Trent and I don’t expect those to go away. Real Madrid are a big, iconic club. Most players might not say it, but nearly everyone wants to play for Real Madrid. If Madrid wanted him, I think it would be a deal that he couldn't turn down. He’s been so successful at Liverpool and won every trophy that you would want to win as a player with his boyhood club.
"If he did decide to go, it’s not like he would be leaving on bad terms. I don’t think anyone would complain or begrudge him a move to Madrid because when Real Madrid come calling with a free transfer, it's hard for any player (to turn that down)."
