I think it was a noble idea of Rodgers to try it - it's a more imaginative and progressive idea than using a conventional DM there - but I just don't think it works when the opposing team targets it as a problem. The odd exceptional player, most notably Pirlo, of course, can collect and release the ball so quickly and precisely that even most man markers will struggle to blunt his effectiveness, but even he has been shut out of certain games because the position is so obviously limited in terms of location on the pitch (the mancs, for example, used Park Ji-Sung to stifle him through sheer persistence). It doesn't help that Gerrard remains a player with such an excitable football brain he can't help but also get dragged away into other areas, not actively but reactively, so he's essentially adding to his own incoherence.
An excellent post. And absolutely spot on.
