I don't understand why they would want to take that risk though. If you're sick of top 4 and want to actually start competing for the league and other trophies then get a manager with those credentials right? It's an almost certainty that he'll deliver to some extent with the budget available to him. Of course, If Tuchel does work out then they have their manager sorted for another Wenger like stint, but it is a gamble. The only club that could of afforded to make such gambles is us I would say. We had been out the champions league for so long the demand for instant success wasnt there, fans realised that we had to rebuild in order to get back to where we wanted to be and that would take time. So yeah, in that case you can take risks with younger different, energetic managers. You are more willing to give them the time. I don't think Arsenal are. Whoever comes in will need to make an instant impact.
