This season is a transitional one. The moment Poch was sacked and Jose came on board, it was all about making the best of the situation.
The long-term injuries to Kane and Son have of course made things tougher so at the moment, while top 4 and the FA Cup remain viable, I would not be surprised if we ended up neither at the end of the season.
The time to judge whether Levy and Mourinho can make Spurs tick once again is next season and the following one. No quick fixes.
