Speaking after the match, Guerrero suggested that referees are biased towards Messi and Argentina.
"It’s a bit difficult to play against Argentina," the 40-year-old told the media. "Every contact was a foul for the referee, but when we were touched, no calls were made. They are a bit tough, but you know how it is."
In a second interview, he added: "We were touched and no fouls were called. You touch Messi with a finger and a foul is called on us all. That makes it a bit difficult because it conditions you."
