Mikel Arteta has made Arsenal stronger than before, but unfortunately, there is one thing he doesn't have, that is the champion mentality, therefore whoever the competitor is in each season (be it Man City or Liverpool), Arsenal has always been under their shadow, and they always ran out of energy when the season was coming to an end. I think Arsenal need that factor because they haven't won a trophy for too long, and for that they need the right manager with strong character. If that is taken into consideration, so it's reasonable if Arsenal needs a new manager to replace Arteta (but the change should not be made while the season is still ongoing).
Yes Arteta has made arsenal really strong thankgod you have acknowledged that fact. Sometimes I really do ask myself why people always have this mindset, whenever the team is not doing they will shift the blame to the manager, in fact if arsenal should like they should be changing manager every season the problem will still be there just like Manchester united that changed there manager but yet the club is still facing the same issues. Until the club should be able to figure out where they are not getting it right, changing there managers won't solve the problem morespecially if the fault is not coming from the manager. Some of this problems may be coming from the management of the team, Arteta has really done well as long as arsenal is concerned.
You correct, He changed many things in the team and after this performance of team became better . He is very intelligent person and he always try to take step for the team members. Arsenal football team became one of the top team of the tournament because that team won many matches of the tournament and have 54 points on the table . But Arsenal team could not win last match and match was ended with draw result because no team could do any goal in this match.Arsenal team has good side but in this match, both teams did well for the defense and no team player took risk .And In the end , no player could do any goal in this match.
