West Ham have made an approach for Stuttgart centre-back Ozan Kabak.
The combative Turkey international has a £13.3million release clause following Stuttgart's relegation and has interest from a number of clubs across Europe, including Tottenham and Bayern Munich.
However, the 19-year-old wants to make a move to a club who are ambitious yet will still afford him regular game time and a platform to develop.
Those factors will be at the forefront of his decision as he ponders his next move.
The Hammers are also increasingly confident of concluding a £24million deal for Villarreal midfielder Pablo Fornals following further productive talks on Wednesday.
Director of football Mario Husillos has pressed for an agreement over the 23-year-old Spain international amid interest from other clubs.
Technically gifted, Fornals prefers an advanced midfield role and will provide competition for Manuel Lanzini who is discussing a new contract.
The Spaniard currently has two international caps to his name, and is set to feature later in the month Under-21 European Championships.
Meanwhile, West Brom have ruled themselves out of a late move for West Ham defender Reece Oxford who was poised to join Augsburg but has still to agree personal terms.
