From previous reading of articles, something common that Iraola and Glasner shared was how they came through poor runs of results. Last season they had to deal with 7 and 8 game winless streaks respectively. However, they managed to overcome the challenge while keeping the players onside.

In short, they come across as managers with resilience, tactical conviction, man-management strength, and long-term clarity.
