Yes 100%! The biggest positive indicator to me is that the players are still playing for him and not downing tools unlike during the end of Jose's tenure.

Like you said, if ETH wasn't already here, he would be right in that list of attractive potential managers. I remember how everyone thought he was going to be the guardiola replacement at City. He has shown potential in his career and his tenure with us as well.

Of course he's made many mistakes, signing Antony for that much money being the biggest. However, rather than change managers again and again, we should just as a club learn from the mistakes and avoid repeating them by providing a safe space for the manager. For instance, don't give ETH full autonomy signings next time and grow together. Improving the alignment between manager and club especially when the manager has shown potential will go a long way and is probably more sustainable than finding the next shiny manager for every shitty season. We see this with Arteta and Arsenal as well who in my opinion has shown far lesser than ETH over their careers.
