Arsenal was not lucky enough during this season and they recently lost their player Mikel Merino who he joined this team just a few days ago. Mikel Merino was the player Arteta wanted to hire him and he tried to get Mikel Merino ready for the games in this season.
He left Real Sociedad and started playing for Arsenal to have the chance to play in strong teams. But in the first training session in Arsenal, he got injured and it seems Merino's going to be out for 2 months.
I have to says this is big lost for Arsenal because Arteta expected Mikel Merino will make his debut match in Premier league besides that Arsenal is really needed him because Mikel Merino can be played as defensive midfielder which for this position Arsenal have no players who can playing consistent and indeed according to the latest news about his injured it says Mikel Merino will be rested for next 2 months or 7 weeks which mean until October Mikel Merino will not be availableHe left Real Sociedad and started playing for Arsenal to have the chance to play in strong teams. But in the first training session in Arsenal, he got injured and it seems Merino's going to be out for 2 months.
This is very unexpected and i have to say Arsenal are unlucky however talking about new player who got the injured on this team i just remember Arsenal has one player who transfered from Ajax Jurrien Timber that this player also has similar problem just like Mikel Merino even more worst because when joining to Arsenal Jurrien Timber got long term injured and he was spend last season to recover from his injured
