Manchester City are ready to add Juma Bah as their next January signing.
The 18-year-old centre-back from Real Valladolid is likely to be sent out on loan to Lens.
Bah has made 12 first-team appearances for the LaLiga strugglers after breaking into the squad in September, on loan from AIK Freetong.
He also earned his first call-up to the Sierra leone national team last May although he is yet to make his international debut.
Towering at 6ft 5in, Bah would become City's tallest player ahead of Erling Haaland.
City have already added two defenders to their squad this transfer window as Pep Guardiola looks to shore up their backline.
