I am not sure anyone would not want us to win the EL who ever is in charge. That would be a tremendous achievement and it's a no brainer that Ange should then get more time.
If we don't win the EL, the decision is more problematic for me. Ange, IMHO, hasn't shown yet that he can win the big games and that's really important for this team's development. Aside from City, (and they of course are having a poor season by their standards) and Villa, we have lost to every other team in the top 10. Not even drawn - lost. It's an awful record. Villa were the outlier result IMHO in that they were doing reasonably well when we beat them.
If Ange can achieve results in games which we might not be expected to win showing he can manage those big games then he should be given more time even if he doesn't win the EL.
If he doesn't win, I think the decision is a lot clearer
- 9th -12th with a >45% loss rate isn't acceptable for a Spurs manager in 2nd season regardless of circumstance/context
- One semi in a domestic cup doesn't change anything
I'd assume he's out in that scenario
The complex scenario is
- He does win the EL
- We only improve our league position to 8th-10th
In both scenarios it would be a tough call but I think logic says he goes (the narrative/fan stupidity associated with firing the manager who actually wins us something will be a dumpster fire)
The scenario where he stays is
- He wins the EL
- We go on a decent run in PL and get back to 6th/7th.
The big risk is we keep him (in either of the first two scenarios), and the first 10 games of next season the wheels come off and we are scrambling for a replacement (the ETH scenario) and said replacement hasn't had a shot to influence transfer window.
