I also think the key point is being vastly overlooked regarding transfers in & out. People say you can't move forward without buying players yet we've progressed to the final of the biggest club competition in the world.
Yes our league form has been erratic but overall can anyone really say that the vast spending done by the likes of Everton, Chelsea etc has really altered our status in the game domestically? We had some erratic results but up until the Burnley game the squad had shown it could hold its own and was within a couple of points of two teams that arguably have produced the most scintillating title challenge the Premier League has seen in terms of quality.
If our form hadn't dropped so poorly we would have been sitting pretty in third comfortably, our form in the early part of the season suggests so.
Pochettino and the players have developed new skills this season, ones more focused on tact and responsive, reactionary levels and that will only hold us in good stead moving forward. The club took a chance, just like a club does when they do end up signing someone and it seems to have been the correct decision based on league and cup competition results come the end of the season so I don't really see why people still have issue with last summer. It's been, gone and the club were proved right based on the outcome 9 months later. Nothing to see here, in top 4, in the final and have twice as much money for our troubles for doing so as and when we require spending it.
