Arsenal signing the Real Sociedad and Spanish midfielder will solidify the team considering the tough matches they are faced with in the beginning stages of the season so they really need to build strong defense and midfield hence signing Mikel Merino is a good development. Arsenal have added some very tactical players to the team this season so we look forward to see a positive change in the team. €33.5 million for the Real Sociedad midfielder is a fare amount and I believe Arsenal will not regret signing Mikel Merino because he is also a very notable player Spain and Real Sociedad so he's gonna do better at Arsenal and it wouldn't take him much time to be accustomed to the team.
