Real Sociedad has left Mikel Merino out of the squad to face Union Berlin in a friendly tomorrow.
Merino is believed to be on the verge of signing for Arsenal this summer.
The two clubs are locked in negotiations over the structure of the deal having broadly agreed terms.
Arsenal have been exploring the conditions of a transfer for the midfielder, who has entered the final year of his deal.
The 28-year-old is keen on a move to Mikel Arteta’s side.
Liverpool target Martin Zubimendi has however been included in the squad.
