We weren't good enough to win the league in either of the first two seasons. The squad didn't have enough depth to remain consistent all season.
The likes of Halliday, Flanagan, Katic, Coulibaly, Lafferty, Grezda, Polster, Middleton, Hastie, Jones, Kamberi, Edmunson as the supporting crew weren't good enough.
When we finally won the league we had a much stronger squad overall and had more players if the required quality. Hagi and Roofe made a huge impact that season. Balogun was excellent for rotating with Helander. Previous to that we were too reliant on the same key players performing and they couldn't drag us through a full season.
He should have won us a treble on 55 season, I don't think that's up for debate. The manner of defeat in the cups that's season was ridiculous. The league cup final in 2019 we should also have won.
I dont think winning those 3 trophies would have really meant much in the grand scheme of things though other than make his tenure look better on paper. The real success was 55 and the European progress. We got way way way more out of the European progression and giving us a reputation again on that stage than winning some more domestic cups would have done.
