Koeman rapped the players' performance after defeat to Sevilla, but Villa said: "Everyone's form is bad. And I say everyone, not just the players, the coach, I insist, everyone. If our form was good, we'd be competing with Barcelona and Real Madrid."
Asked if he had learned anything from Koeman since the Dutchman's appointment, Villa replied: "I do not know, nothing concrete. I attempt to learn from all my trainers, but no-one teaches you to be a better forward nor how to shoot or finish."
