Mesmerised By Raccoons
Arteta is a great modern coach, highly capable to break down a general philosophy into many small pieces, and then drill them into the team. That’s what modern tactics is all about, and he is great at it. However, his philosophy is just terrible. No matter how capable you are to drill the tactics into your team, if you based it on a bad philosophy, you won’t get results. To me, he is the polar opposite to Wenger in terms of tactics. Wenger has a great set of tactical philosophy, but he failed to adapt to the modern tactical practice to drill pieces of small instructions into the team. In an ideal world, it would be great to have Wenger as a manager and Arteta to be the assistant. That would be a world class setup because the strengths of Wenger is the weaknesses of Arteta and vice versa.
What are you basing that estimation on exactly? A great modern coach is not a descriptive to throw around lightly, so what is it based on? Have you worked with him? Attended his team meetings? Do you know him personally? Because other than that only team play can tell you anything substantive, and in now way could you have reached your estimation from what we see on the pitch.
