After Stuttgart were condemned to the 2. Bundesliga following their defeat in the relegation play-offs, a host of clubs will now attempt to land centre-back Ozan Kabak.
West Ham, Tottenham, and Bayern are all said to be interested in the 19-year-old, with the Hammers reportedly making an approach.
The Turkish youth international has a £13.3m (€15m) release clause and desires a move to a top-flight club that can offer him regular game time.
Kabak just joined Stuttgart from Galatasaray in January in an €11m and made 15 Bundesliga starts, scoring three goals.
With the Turkish outfit, Kabak made four Champions League starts.
Meanwhile, the Hammers are on the verge on signing Villarreal midfielder Pablo Fornals for £24m. An announcement could be made as soon as this week.
