The Brazilian started alongside Gary Cahill, who was also back after hamstring trouble, with the pair the Blues’ only eligible regular centre-backs due to the suspensions of John Terry and Branislav Ivanovic.

“I remember I missed a penalty in Genk at the group stage. Missing it and thinking about it was something that kept me awake for a few days. It was not nice,” he continued.
"I missed the final games [of the season] and I was so sad, but this penalty was waiting for me. I knew in the shoot-out I had an opportunity to put everything right, to score one that people, all the fans, would remember.
“So I just did what I always do in training, had faith in myself and what I was going to do. I’ve always taken them that way. I am glad I did what I intended to do and scored.”
