The penalty to Semedo changed the future of Rayo. It was at least controversial: "He touched me, I do my job and I let myself fall in. I felt the touch that you have seen on TV and you are aware that it is a penalty", said the Barcelona player on the play that decided the match.
Valverde's team was only tied when that play happened in the area. The controversial play defined the match and has not agreed to almost anyone.
For almost everything there is contact, what is not clear is whether it is enough to indicate a penalty. Semedo already makes it clear that he does his part when he feels the touch of the player rayista.
