Former Liverpool boss Jurgen Klopp is an admirer of RB Leipzig striker and Arsenal target Benjamin Sesko. The German tactician lauded the Slovenian forward, stating he was impressed by Sesko's performance even when he played at RB Salzburg.Jurgen Klopp told reporters in January earlier this year (via TBRFootball):"I was pretty impressed, he played a good game. He's a good player anyway. I've actually known him for a while, I knew him already when he was at Salzburg. I think we played a friendly game here when he was very, very young. I was really impressed. I thought, where do they get all these players? Ridiculous."The Gunners have been reportedly interested in signing the 22-year-old for a long time. Arsenal wanted to land Sesko during the winter transfer window; however, the Slovenian forward decided to stay at RB Leipzig.According to Fabrizio Romano, the north London club's sporting director, Andrea Berta has begun concrete tasks with the Bundesliga side for Sesko. Mikel Arteta also holds the 22-year-old in high regard as the Gunners are keen to sign a reliable attacker.The Slovenian attacker has made 87 appearances for Leipzig across competitions, scoring 39 goals and providing eight assists. Sesko's current deal with Leipzig will expire in the summer of 2029, but he could be available for £59 million this summer.Arsenal close to signing contract extension with defender: ReportsArsenal are reportedly in advanced talks with Brazilian defender Gabriel Magalhaes over a new contract.
