Maybe he had to play second string to keep his team in Champions League next year? I rather enjoy the way he approach a loss. Rarely excuses. Rarely pointing to others. Rarely moaning. I know a guy who could learn a thing or two.

In each competition Pochettino enters there are usually at least four teams that have spent close to twice as much assembling there squad as him. For him to win a conpetition where one of these teams enters, it is not enough that he «overperform». The gap in resources is to big. The other teams have to «underperform». Not one, but all four of them. That will rarely happen.
That he consistently beats one or two of these teams, coached by Klopp, Conte, Pep and Mourinho is so impressive!
You can also note that the gap between Arsenal and Spurs used to be a lot bigger. But the success of Pochettino has helped close the gap. That imply that he, over the last four years, has consistently performed better than three-four teams with a lot more resources.
He could prioritize differently to win a trophy. But he would be stupid to do so. The most important thing for Spurs is to stay in the Champions League. They could do that by winning the Europe League, but the element of «chance» is bigger in the Europe League.
Furthermore, I think we should remember that the most important difference between a club that has spent €673-976 mill and a team that has spent half that is the level of their substitutes. Man Utd, City and Chelsea could probably field two teams that costs more than Spurs first team. That will hamper the possibility of rotation greatly.
I must also say that I’m so impressed by the results of Spurs so far. They had a really tough build up to this season with a lot of england and belgium players, but are just two points behind. (The were also very unlucky not to get a penalty in the final minute against Liverpool.)
