Gavi and gundo were teared apart with romeu entrance and xavi disasterclass. Ancelotti like a drunk pirate didnt even realise that with modric entrance he had camavinga, modric, valverde and bellingham against gavi, gundo and romeu. To be more precise, you had four of them against gavi and gundo.
They were losing control before that and physically struggled to keep up with Real as game went on.
Both on ball and off.
Romeu made it worse but as a whole midfield lost control.
