Mateo Kovacic
Whilst Weigl is key to his side Kovacic is, currently, not to Real Madrid. He faces the unenviable task of dislodging Toni Kroos and Luka Modric from Los Blancos’ line-up whilst Casemiro also gets the nod as back-up ahead of him. He’s a talented player without doubt, though, and that is why the Gunners should consider offering him and his career a lifeline.
