Very interesting topic. While I firmly believe that with our best midfielders in form and playing our 4-3-3 our midfield is good enough for what we need it to do its rather a question of style rather than ability. To understand the reasons that caused such a question I feel we need to dwell in this squad's history ('istoree for you lurking Scousers). Ever since Mourinho we've been playing a brand of football that suits midfielders like Essien and where technical ability isn't vital. Our direct football brought results more often than visually attractive play. Roman's wish for a more attacking style was one of the reasons he hired Scolari who for all his faults turned us into a pretty impressive side in his first few months only to be let down by a squad that didn't match his vision. One of the main reasons behind Hiddink's success was that he opted to switch back to Mourinho's more defensive and direct tactics which our squad (read: midfielders) was designed and build for. Ancelotti, to his credit, took a far more attacking approach than his predecessors and (again to his credit) managed to get results out of that team along with very impressive football at times. While last season he did succeed in marrying our squad and his football I believe that at the end of the day our current midfield options don't suit the football he tries to play (not good enough, if you will). It'll only become even more painfully obvious if the switch to a midfield diamond isn't temporary. What's interesting now is what our club (Football Board + Ancelotti) plans for the future. While signing an Essien clone in Ramires probably points towards us continuing utilizing the "runner" type of midfielders its worth noticing that the majority our our young mids (Mikel, Kakuta, McEachran or even Matic who was a CFC player only a month ago) are technically at least equal to anyone we had in Mourinho's days.
