Should have never hired Potter in the first place, guarantee had we gone for Pochettino we would be at least in the top 6-8 maybe top 4. We would have seen some progression in the way we play along with individual development.
Those that are hating on Pochettino are either highly bias because of his Spurs time or are taking their disain for the board out on him.
I promise we could do a lot worse than Pochettino. Huge upgrade on Potter, with so much more experience in the elite level of football.
Created a recognisable and entertaining style at Southampton and led them to 8th place. Fun fact aside from his first season 14/15 (a great season for us) in which he took Spurs to 5th (one place higher than their previous season 6th) every other single season he was at Spurs they finished in the top 4.
So 4/5 seasons he had them in the Champions League and considering the only year he didn't was his first year I think that's quite impressive. Even more impressively the only time they were 4th was his final season he managed two 3rd place finishes and one 2nd place finish.
He took Spurs to their highest point total in the EPL 86 points 16/17 season (another great season for us). He was also the coach that ended our 13 winning streak that season not even by a draw but by defeating us and tactically it was an impressive win. He identified a weakness and exploited it. Took Spurs to their first and only UCL final beating Pep's Man City and probably the most entertaining side in the competition ETH's A**x in the process.
Helped develop Son, Kane, Dele Ali and Eriksen all into top players during his tenure. Took them to a league cup final like Mourinho (before he was sacked the week of) and coincidentally lost to Mourinho's blues (as I'm sure you remember 14/15 was a good season for us).
Knocked out Bayern in the UCL in his first half season as PSG coach not spoken about enough since Bayern were the current holders at the time. Lost to Pep in the semi finals which is no shame. The next season they lost to a Madrid side that just wouldn't die. I would argue the capitulation can't be all his fault. His keeper and defenders threw that go back and watch it no coach has control over that.
The dude won 3 trophies in 1 and a half seasons in charge, which is an impressive rate since thats what Tuchel did for us, sure the UCL is much more valuable than Ligue 1, but you get the idea.
By all means dislike the guy, dislike the board but don't make out he's not a good coach or he's not good enough for us. Where we're at right now, we're crying out for a top coach and if you can't see Pochettino is a top coach you're either heavily bias or have questionable understanding of elite tactics and coaching.
On a final note if you consider the budget he worked with at Spurs especially compared to his rivals and the fact he achieved relative success i.e consistent top 4. This all screams top quality coach.
