No, that's wrong. However:Lucas before his injury was verging on world class. The injury fecked him. Agger of a few seasons ago probably was very close to world class too.
Lucas became world class during the injury. The longer he was injured, the better he started to become in the eyes of RAWK and most of Liverpool supporters. After few months of him missing, he became world class. Then, he became the best defensive midfielder in the league and later during his spell out he became the best defensive midfielder in the world. If only the injury had lasted a bit longer, he would have became the best defensive midfielder of all time and arguably the best player ever.
Unfortunately for him, the injury ended and with that ended his rating. He became as useless as he was before the injury.
