Fotomac reports that VfB Stuttgart is among a group of clubs tracking German Köln midfielder Eric Martel. The report also names Celtic, Beşiktaş, and Fiorentina as interested parties. The 23-year-old is considered a realistic option for the summer transfer window as he is in the last year of his contract. Martel's flexibility increases his appeal, as he has frequently played as a holding midfielder and can also play in defence. The former Germany U21 international joined his current club in July 2022. He has 30 caps and 3 goals for the U21 team. This season, he has made 27 Bundesliga appearances, scoring 2 goals and providing 2 assists. Transfermarkt estimates his market value to be €8.00m.
