Liverpool legend Phil Thompson has urged the Reds manager Jurgen Klopp to complete a left-back signing before the end of the summer transfer window. The Anfield favourite wants his former club to sign Chelsea target Jonas Hector to bolster the back four to boost their chances of winning the title this season.

The former Borussia Dortmund boss has the services of Alberto Moreno as the first left-back in the Reds squad. He also has James Milner, who can play in that position. The Spaniard was criticised for his performance during the Merseyside club's 4-3 victory over Arsenal at the Emirates.

"I don't think you can get carried away when your team defend like we did against Arsenal. I always fear defensive mistakes," Thompson told Sky Sports.

"Left-back is obviously an area that Liverpool are looking to strengthen because there was talk that if (James) Milner was fit he was going to start there. I think more Liverpool fans would like to see an out-an-out left-back to compete for the position."

"I did think that Klopp would go for Germany's Jonas Hector, who is first and foremost a good defender and also decent at getting forward, which is the way it should be," he added.

However, Kloop defended Moreno's performance after his side clinched their first three points of this campaign. However, Thompson believes the manager must replace the ex-Sevilla man with Hector before the transfer window shuts on 31 August.

Thompson further said, "He [Kloop] has come out and supported Moreno, which he has to because you don't know when you need the player, but there's two weeks to go and you'd imagine he's still in the market.

"The biggest problem is his poor concentration, which result in rash decisions. There was one headed clearance and another right-footed clearance that went across his box. It's decision making in the vital areas."

Hector, the FC Koln defender, has signed a new deal earlier in August. Despite that, the Mirror claims the Blues boss Antonio Conte is willing to make a £20m ($26.2m) approach for the German international's services.
