West Ham great Paolo di Canio rapped Timo Werner after Chelsea's 1-1 draw at Real Madrid.
Werner missed an open goal during the Champions League semifinal first-leg in Madrid.
“The attitude was wrong, it's not a finish you expect from an important player," Di Canio told Sky Italia.
“It seemed he was playing a game with his friends.
“Sometimes his teammates could have served him a little better, but his movements were not convincing and often he was not in the right position. Werner is very fast, but he is too frenetic too."
