Mariano Diaz Mejia is poised to rejoin Real Madrid before the close of the summer transfer window in Spain on Friday, leaving Sevilla furious.
Having risen through the Blancos youth ranks but failed secure a starting berth in the senior squad, the forward joined Lyon last July and enjoyed a stellar campaign in Ligue 1, netting 18 times in 34 outings.
Mariano's fine form is set to earn him a rapid return to La Liga. Below, though, Goal explains why Sevilla are so upset that the 25-year-old is bound for the Santiago Bernabeu rather than the Ramon Sanchez Pizjuan.
