When we spent 30million on him, he was worth that though, we spent it when United had the "best" squad in Europe, and didn't need 3 or 4 players, just a few refinements, Berba was not used correctly or performed well enough in his first season, Which made him a bit of a scapegoat for the next season, which he actually supported Wayne well, with plenty of chances/ passes, but this was over looked due to the fact he wasn't scoring freely and Wayne was in such great form, the term "one man team" was thrown about by just about every other clubs supporters, when most United supporters realised what Berba and other players brought to the team, whilst Wayne was taking all the headlines. Then this season, he has stepped up brilliantly when required, an Hat trick against Liverpool when we really needed it, we where so poor going forward at this stage, he looked like the only player who was ever going to score a goal. Then he again turned supplier for Hernandez when Wayne was out( our normal deeper laying striker) which helped the young Mexican become an instant success, so all in all, he has been one of our better players this season. and got himself 11 EPL goals for it, the same he had all of last season. So now he isn't worth 30million, but given the circumstance and his ability 3 years ago, he was well worth buying.
