Reports suggest that Liverpool have been monitoring Villarreal's left-back Sergi Cardona for the past 18 months as they consider strengthening that position this summer. Cardona has impressed in La Liga and appears to be a viable option for the Reds to consider, although he may not be their top choice for the role. It is understood that Liverpool have been thoroughly researching the player, but they may favor someone with more Premier League experience. According to an in-depth report by the Daily Mail, Cardona is among other notable players such as Milos Kerkez and Jorrel Hato on Liverpool's list of potential targets for the summer transfer window. The 25-year-old is viewed as a promising prospect to watch, but Bournemouth's Kerkez is reportedly a better fit for the team, which already includes Andrew Robertson and Kostas Tsimikas in the left-back position. Liverpool are evaluating these options as they look to find a long-term replacement for Robertson, who is reportedly beginning to show signs of decline this season.
