Arteta is a good manager in every way. He is both a coach and a recruiter for his team. Arteta was spotted last week at the Real Madrid U18 - Atletico Madrid U18 match. I think he is looking for more players for Arsenal in this match. I can see how eager he is. If Arteta is there for Arsenal, he could be laying the groundwork for a squad that will be talked about for many years to come. I don't think there is anyone better than Arteta for Arsenal at the moment. If Arsenal become premier league champions after 20 years, Arteta will be on a different level.
No doubt Arteta is a good manager, he already made Arsenal be a strong team again. In the last 2 seasons, Arsenal always joined the race for the title. Even in the current season, Arsenal is leading the EPL standings, they are a great team under Arteta management. If he watched the match Real Madrid U18 vs Atletico Madrid U18, he is very likely interested in certain young players of both teams. I guess Arteta may have a plan to sign youngsters of Atletico Madrid.
Yes, Arteta has the chance to give a trophy for Arsenal. But the competition is very tight, Liverpool and Man City won't let Arteta to win the trophy. However, if Arteta can beat Guardiola in the next match, I think Arteta will have the chance to win the EPL trophy for this season.
