Injury blow for Arsenal as Arteta confirms new signing will be out for weeks

Mikel Merino completed his move from Real Sociedad to Arsenal for a fee worth £31.6 million, including performance-related add-ons.

The midfielder signed a four-year contract deal at Arsenal, with the option to extend for a further 12 months.

However, following his move, he suffered a terrific injury in his first training session with the first team.

Merino has been confirmed injured by Arteta after a collision during training, leading to shoulder damage to the player.

According to the Mirror, Arteta said, "Yes, very unfortunate. Yesterday he had a collision and he has a shoulder injury. It looks like he’s going to be out for a few weeks.

"He was really excited and everything was looking really good. He landed on the floor and Gabi landed on top of him and it looks like he has a small fracture probably."

Arteta suggested that the Spanish midfielder landed badly on the floor and one of his teammates fell on his hand, leading to a small fracture.

Merino will now undoubtedly miss the match on Saturday against Brighton, as well as the matches in September against Manchester City, Tottenham, Bolton Wanderers, and Leicester.
