Diego Simeone is reportedly set to capitalise on Mikel Arteta 's transfer error and steal Arsenal star William Saliba from under the Spaniard's nose.
Saliba is still yet to make his senior debut for the Gunners, despite signing for the Premier League giants three years ago. Instead, the defender has been sent out on a series of loan moves, all back to his native France.
His latest move to Ligue 1 has been to Marseille, joining Jorge Sampaoli's side for the duration of the current campaign. Saliba has thrived at the Orange Velodrome, becoming a key part of Sampaoli's starting defence.
