Kerkez was replaced by Robertson in the 38th minute of the game, which Liverpool won 1-0.

Robertson praised Kerkez' performance, saying: “He has come in and was fantastic for Bournemouth last season.

"He's only young and I think we forget that, all the new signings are young but have incredible potential and they are the future of the club and you try to help them as much as you can.

"But you want to put pressure on them and you want to play games.

"He will be the starting left-back for Liverpool in the future and it's up to me to push him this season and help him improve.

Kerkez has made a big transition to Liverpool after playing for Bournemouth, but Robertson believes he is adapting well to the new challenge.

“It's a massive jump,” Robertson said.

"I came from Hull, he's come from Bournemouth and it's probably quite similar.

"There are a lot more eyes on you in a Liverpool jersey than it is than those two clubs.

"He has transitioned well, there's a lot of information and a lot of different ways of playing and he just needs to keep going and keep his confidence.

"We'll try to help him and others throughout the season and I have no doubt in the future he will be a fantastic left-back for Liverpool and that's the main thing."
