Villa were unhappy with the penalty award by referee Jon Moss as they felt there was no contact on Suarez after he went past Guzan.
The goalkeeper said: "I asked (Suarez) - because I was pretty confident in myself I hadn't touched him - 'Did I touch you?' and he said 'I don't know'.
"That is the honest truth of it. Sometimes they go for you, sometimes not.
"Obviously the referee has given it but at the time I thought I pulled my hands back and I don't think I made contact with him.
"I don't know if the referee can see that or not as I don't know his positioning. From my point of view it is probably a soft decision.
"I think Suarez was probably a bit surprised to have it given but those are the decisions and you have to get on with it and go again."
