This Spurs squad isn't a great fit for Postecoglou, but he'll get them playing football much more suited for creating chances, which has been one of their biggest weaknesses in recent seasons. He'd need some time to reshape the team and no doubt need a handful of signings that would enable a more progressive game.
I can't work out how good he is to be honest. Let me preface this by saying as a Rangers fan i'm obviously biased, but i try to be as fair as possible.
He'll have won a double and a treble in his first 2 season, so he can't do much more domestically than that.
However, in saying that, i think last season the whole Gerrard being a bit unsettled then eventually leaving helped play into his hands, and i dont think his replacement (your namesake) gave him much resistance in terms of league form.
However, since Michael Beale has came in, with a squad that's bloated and unbalanced with many who knew they were leaving, i think he's performed well in comparison. I think he's matched (or bettered) his league points since January, and lost by the odd goal against them in the cup competitions. I would have thought a settled Ange Celtic team would have played Rangers off the park in these games and they didn't.
Don't get me wrong, I rate him, he plays high press, high energy front foot football from the off, and he is brave where he plays it no matter the opposition (which i think is a bit naive at times in Europe to be honest), but it is great to watch. What i don't know is
how good he is considering his lack of challenge domestically, and i think we would see that answered next season more as i think Beale's Rangers will put up more of a challenge than Gio's Rangers.
