That's why Arsenal signed Mikel Merino for a fairly long period of time. So hopefully Mikel Merino can quickly resolve his contract problems with Arsenal and be able to play with Arsenal soon. Because Mikel Merino will of course be very important capital for Arsenal.
Arsenal are very serious about their team this season. They don't want to be the guard first ranked and fail at the end of the season. This proves that Arteta is very active in adding new players. Meanwhile, Merino should just have to wait for time. I read Merino had a medical test, I think it was only a matter of time. Merino has also played at Newcastle United. The statistics in Sociedad are also quite good. He played 32 times with 5 goals. He can be a creative midfielder to overcome Arsenal's stalemate.
Arteta continues to build the Arsenal squad to be better and better. And yes, with the addition of Mikel Merino, it is hoped that this team will become even stronger. And we know that Mikel Merino is indeed a player who has sufficient experience at other big clubs. So when he comes to Arsenal, he won't need a long time to adapt directly to Arsenal's style of play coached by Arteta. This player's medical examination also went smoothly. And now they are probably exchanging documents and signing every file required for this player's transfer and his contract at Arsenal.
