We're missing Essien more than we're missing Ballack imo. Ballack's been replaced with Ramires, it's Essien who's gone missing most of the season. Add to that Lampard's and Benayoun's injuries and you see why we struggle for rotation (Lampard) and creativity (Bena). Could have been solved by getting a playmaker in Jan, but no, we'd rather splash 50 million on a striker and 26 million on a defender than address the real issue by getting flair and vision in that midfield. I've been saying this all along - we need creators, not finishers.
