He was able to adapt the tactics and team to the opponent, which is a far more stable team and better team for the most part.
Real Madrid also had less possession than Liverpool in the CL Final, only had 4 shots with 1 on target, and yet won. Courtois also had a MoTM performance, while DDG tonight made a few good stops and interventions, but nothing like Courtois.
A very good game plan and the subs were spot on. He's an astute learner and manager. He's made distinct changes after the first two heavy losses and tonight was another match where he shook it up and found a lot of positives.
