Arsenal are in talks with Real Sociedad over the signing of midfielder Mikel Merino.
There is work still to do on the deal, but Merino is understood to be keen on the move.
An agreement on personal terms is not expected to be a problem.
Merino, 28, has a year left on his contract.
He featured in all seven games for Spain at the Euros – scoring the winner in the quarter-final against Germany.
