Mason Mount admitted surprise at earning Chelsea a penalty in Milan and shock at Fikayo Tomori's red card.
Former Blues defender Tomori was sent off 18 minutes into Chelsea's 2-0 Champions League win at AC Milan on Tuesday night.
The England centre-back saw red for tugging back Mount in the area, with Jorginho converting the penalty.
Mount revealed his sympathy for close friend Tomori, with the Chelsea midfielder believing the red card was harsh.
'He's obviously my mate, I've known Fik for a very long time and I felt for him in that situation, I was gutted for him,' Mount told Chelsea's official club website.
