Robertson, 31, replaced new signing Kerkez, 21, in the 38th minute of Liverpool’s late 1-0 Premier League win over Burnley on Sunday (September 14).
The young Hungarian had picked up an early yellow card and looked like he could very well pick up a second in a manic performance.
Kerkez may have supplanted Robertson in the starting eleven, but the Scotland international can sympathize with his new teammate.
He said: "It's a massive jump. 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 at those two clubs.
He (Kerkez) 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. I have no doubt in the future he will be a fantastic left-back for Liverpool and that's the main thing."
