What has Villa done exactly that Ibramovic didn't?

i don't think it was off-field antics as much as it was his antics in general that sealed his fate (talking bad aboutt he coach def didn't help). you could tell ever second that went by where Ibra didn't score, he would be more and more disappointed. even as a center piece player who could distribute the ball amazingly around the top of the box to create goals, he was never satisfied with himself and more importantly the team unless it was him who was scoring. Villa is not a better striker than Ibra for sure, but his drive and attitude was a lot more cohesive with Barca than Ibra's.
