BREAKING: Arsenal hit with major Gabriel Magalhaes injury blow during Champions League clash

Gabriel Magalhaes suffered a knock in Arsenal's clash against Olympiacos and was quickly replaced. The Brazilian defender was replaced by Cristhian Mosqeura.

Gabriel was marched off the pitch by physios as Mikel Arteta appeared to take a precautionary measure. The physical defender came out worse for wear after a collision with the opposition goalkeeper, having appeared to pull up shortly before.

The centre half took his place in the dugout among his team-mates rather than heading down the tunnel for further treatment by Arsenal's medical staff.
