Thomas Tuchel has sounded a warning about Carlo Ancelotti's friendly relationship with referees ahead of Chelsea's clash against Real Madrid.
The Blues' only chance of silverware this term is to claim Champions League glory, although few expect them to achieve it. They are firm underdogs against Los Blancos, who won the competition last season and beat Chelsea, then managed by Tuchel, en route to the final in Paris.
Madrid won 4-3 across the two-legs with Karim Benzema bagging the winner in extra-time. Tuchel though took issue with how Ancelotti and referee Szymon Marciniak interacted after the game. The pair appeared to share a joke as Tuchel wandered over, which sounds as a warning to Frank Lampard, who is set to be in the Chelsea dugout next week as he plots a shock victory.
