Former Premier League striker Gabriel Agbonlahor has suggested that Kostas Tsimikas accept the regular selection of Andy Robertson over him in Liverpool's first team. He has asked the Greece international to keep improving and fight for a place in the starting XI.Tsimikas has played 18 times across all competitions for Liverpool, but is still the second choice behind Andy Robertson. Liverpool boss Jurgen Klopp has rotated his squad, and Tsimikas has featured more often than any other backup defender.Despite putting in some solid displays, Tsimikas has not been able to usurp Robertson as the first-choice left-back because of the Scot’s consistent displays.Anfield Watch@AnfieldWatchKostas Tsimikas:"When I first came to Liverpool the first game the team played was the Community Shield against Arsenal at Wembley, so for me this will be the second final with this jersey, with this family." #awlive [lfc]4:14 AM · Feb 21, 20225073172Kostas Tsimikas:"When I first came to Liverpool the first game the team played was the Community Shield against Arsenal at Wembley, so for me this will be the second final with this jersey, with this family." #awlive [lfc] https://t.co/c7ZR71fiFvAgbonlahor explained that Tsimikas will have to fight for his place in the lineup as Robertson is one of the best players in his position. Agbonlahor told Football Insider:“Robertson and Trent Alexander-Arnold are the first names on the teamsheet if they are fit. It doesn’t matter about Joe Gomez, it doesn’t matter about Tsimikas, they are just that good. Unless they had a severe run of poor form they are in the side.“It’s good to have competition. Chelsea had Ashley Cole and Wayne Bridge battling it out for years and that took Cole’s performances up a level. I’m sure Klopp will be happy to have two quality left-backs.“Tsimikas will be frustrated but you’re at Liverpool, you’re at a big club and you know there are players ahead of you. I’m sure he will want to play more but you understand that when you’ve got one of the best in the world in your position you’ve got to suck it up and fight to get in the team.”Andy Robertson has been crucial to Liverpool's success in recent years under Jurgen Klopp. The Scot joined the Merseysiders in 2017 from Hull City and has gone on to make 206 appearances across competitions, scoring six goals and giving an impressive 49 assists.He was instrumental in the Reds winning the 2018-19 Champions League trophy and the 2019-20 Premier League title. Liverpool’s Tsimikas one of the best second-choice left-backs in the leagueThere’s perhaps not much salvation in being called one of the best second-choice left-backs in the league. However, Tsimikas’ impressive displays have placed him in Jurgen Klopp’s good books.Klopp used several players in the right-back role when Trent Alexander-Arnold wasn’t available or needed a breather. However, Tsimikas has always been the go-to man on the opposite flank.Anfield Watch@AnfieldWatchKostas Tsimikas:“I enjoy life here a lot. I enjoy life in England and I enjoy life as a Liverpool player a lot. Obviously the first year was not as I hoped and was the most difficult year of my career so far in football." #awlive [lfc]4:12 AM · Feb 21, 20226183221Kostas Tsimikas:“I enjoy life here a lot.

He has impressed with his crossing abilities, putting 83 across with a 23% accuracy. He has created three big chances and given eight accurate long balls. Defensively, he has made 46 recoveries, won 42 duels and made 21 tackles.
