Atletico Madrid coach Diego Simeone risks losing two frontliners to the Saudi Pro League.
Atletico defender Stefan Savic and midfielder Marcos Llorente are both targets for Saudi clubs.
Al-Shabab are launching a 14m bid for Savic, 32.
The stopper is tempted by the move after spending eight years with Atletico. He has a deal to 2024.
Meanwhile, Al-Ahli are interested in Llorente, though at this stage in his career, the midfielder isn't pushing to leave.
