Mount's response after scoring the goal which ultimately put the tie beyond Los Blancos was equally as intriguing.
"I saw one of their players say that none of our players stop him from sleeping, maybe he should lose a bit of sleep for our team, we could have scored more than five goals," Mount admitted to BT Sport.
Kroos responded to Mount last night.
"I'm still sleeping well, but well done yesterday. Congratulations and good luck in your first Champions League final," Kroos posted on Twitter.
