Postecogulu had a poor season with Tottenham, and winning the Europa League is a significant achievement, but their results in the Premier League were frankly bad. Espiritu will be very difficult to replace, and I think that Tottenham will not progress much with Postecogulu, although I hope I am wrong. Nottingham showed a very good game and I think they had the space to progress, but for this they need good funding for new transfers, and if this is not there, then changing the coach will not change anything.
Ange had a bad time with Tottenham last season in the Premier League but won the Europa league because he made his decision to prioritise the Europa after their poor Premier league start due to injury that affected their key players. Tottenham aim was to end their trophy drought and Ange helped them to achieve that mission. I learnt there was issues between Nuno and the owners regarding recruitment that led to his sacked. Everything concerning this process was shocking from the sacked of Nuno that came unexpected to the appointment of Ange who just lost his job.
