Looking back at Chelsea's Champions League exit against Real Madrid, a burst of energy off the bench would have been nice.
Carlo Ancelotti was spoilt for choice having the likes of Eduardo Camavinga on the bench to replace Toni Kroos. On the other end of the dugout, Thomas Tuchel wasn't so lucky. Going into extra time is never ideal for a tired team, and as we are now learning, a tired N'Golo Kante is even worse.
There's a reason why Liverpool and Manchester City are proving to be ahead of the Blues, and the Champions League showed us why.
