This is the first rational response I've seen on here, and I can appreciate where you're coming from but surely the planning for the club takes into account key people in key positions such as Kane, Ali, Pochettino etc. If you lose one of them you could find yourself out of the top 4 and out for a while. Things only go from bad to worse at that point.
For me, there's an element of 'make hay while the sun shines'. Portsmouth and Wigan won the FA cup, Leicester and Blackburn won the league. No matter what bad times came after those events, those fans still remember and still talk about the day they lifted the trophy, being at Wembley, the feeling around the town after the achievement, the lot. By surrendering that opportunity with this squad, you're in danger of never achieving anything. And I appreciate a late point taken at Camp Nou is exciting but it's not quite the same as putting one over Chelsea or Arsenal in an FA cup final, which match are you going to make a song about to sing for the next 50 years?
For me, to see how good Pochettino really is, you have to ask more from him and this team. Your second string isn't nearly as bad as he makes them out to be and he should be doing better with the squad as a whole, despite the poor summer, the squad didn't happen overnight. I'm not saying he should be sacked for not winning a trophy but as a collective, the Spurs fans and board should be expecting the club to win something in the next season or so otherwise he's got the cushiest job in world football right now.
