Shkodran Mustafi may have signed with Levante this summer but the former Arsenal man has been blocked from registering for them due to a number of errors with his squad number.

It wasn’t until late in the transfer window that Shkodran Mustafi finally found a new home but in Levante’s efforts to register the German defender, who admitted he is more ‘worker’ than talented footballer, they made a number of errors.

Mustafi signed for Levante on 2 September, signing a two-year contract that comes with an option of a third.

Levante have given Mustafi the number 13 shirt, which was just asking for trouble, and that’s exactly what they got.

As well as being an unlucky number, for an unlucky player, it’s also only allowed to be used in Spain for goalkeepers.

Levante mistake number one.

They then compounded this error by giving Mustafi a shirt number that has already been used by another player. La Liga rules do not allow players to change their numbers during the season.

Reserve goalkeeper Aitor Fernandez wore the 13 shirt twice before Levante allowed Koke Vegas to leave and promoted Aitor, giving him the number 1 shirt.

As a result, Mustafi is still not listed as a registered Levante player according to Marca, with La Liga less than impressed.

Levante, for their part, don’t believe they’ve done anything wrong but at the time of writing, La Liga still hold that Aitor is number 13 and Mustafi is not in the Levante squad because he doesn’t have a number.

Facing ‘federal’ punishments, Levante will hope to somehow clear the matter up before they face Rayo Vallecano on 11 September.
