I get the love for Pocchetino, but we shouldn't forget that he's managed Spurs without any real pressure and of course he hasn't won a single trophy.
If we want trophies, it might be wise to bring in someone who's actually won trophies (such as three CL trophies), put out an attractive brand of football doing so and has unsurpassed credibility.
I'm not sure Pocchetino would want to leave an ideal situation with Spurs to take on this challenge, anyway.
We don't need trophies in the short term. We need a manager that knows how to implement an attacking style of play and build an actual team. The trophies come afterwards. There is no instant solution to the mess the club is in right now.
Pep didn't win anything in his first season at City, and he had a better squad at his disposal than we currently do, but he's made the right signings (at a ludicrous price, but it's not like we've not spent shitloads on flops at the same time) and has implemented his style of play to the point where they look unstoppable in the league. Klopp has yet to win a trophy at Liverpool, but any old fool could tell you they're on the right track and arguably closer to the league title than they've been in the last 25 years.
Pochettino has done a great job at Spurs and has them firmly in the top four every season. He's the right man for what we need right now, which is a long term plan and some fecking progress, instead of hiring some boring feck every two or three years who spends billions, wins an insignificant cup and then runs himself into the mud and has the entire playing staff and 90% of the fan base hating his guts before getting shitcanned.
