Luiz Suarez is quite inconsistent in his performances and playing for a club which plays mostly attacking football, people expect more from the striker. Whereas Cristiano playing in a league with defensive minded teams and playing for a defensive minded team himself has exceeded the expectations.
He had scored amazing, key goals all season. He’s scored a hat trick vs Madrid. He is not inconsistent. He has over 20 goals in 28 games which is almost a goal/per game and that does not reflect inconsistency.
