After coming on as a second-half substitute, Griezmann made an immediate impact, scoring two minutes after coming on, and thanks to an excellent performance by Valencia goalkeeper Mamardashvili made several superb saves to prevent Atletico from adding to the tally.
Griezman joined Barcelona only with Messi, he played well, but when he left Messi began to fail to develop his game and return to Atletico Madrid, it was as if only coach Simeone understood Griezman's style of play.
By the way. Even though they lost, I can see that Valencia has started to do well since being coached by Gattuso.
