Chelsea keep a close eye on €25m-rated Bundesliga wing-back

Chelsea are prepared to fork out €200m to sign newer footballers and compete for the league title as well as the UCL. While the priority is to sign new defenders and strikers, the Blues are also looking to add a wide footballer. One of their premier options Alonso could be ready for a move away from Chelsea amid interest from Barcelona.

Although the Blues have not particularly targeted a certain individual, they are keeping tabs on Filip Kostic. Currently plying his trade for Eintracht Frankfurt, Serbia international has been a revelation at the German club over the past couple of years.

Kostic has transformed himself into one of the most dangerous wide footballers in Europe, thanks to his ability to whip in crosses into the box. Filip also brings a lot of energy and experience to the table, making him a shrewd option for the Blues.

With Alonso ready to leave the London club, the 29-year-old attacker could prove to be a wise investment for Chelsea as the German manager looks to add competition for Chilwell ahead of the new campaign. The Serbian attacker has enjoyed immense success in the Bundesliga.

But the Serbian could undoubtedly fancy putting his skills to the test in the PL, where his crossing prowess could become even more effective. The Blues, though, are keeping their options open by targeting other footballers in the market.
