Much has been made of Chelsea's galaxy of attacking stars over the course of the summer, with Jose Mourinho's fridge stocked with the kind of offensive talent other managers not named Pep Guardiola, Carlo Ancelotti or Gerardo Martino can only dream of.
However, while the attacking midfield line is well-stocked and Mourinho still has a group of excellent defenders to work with, there is little balance elsewhere.
Up front, Romelu Lukaku, arguably the club's best striker, has been allowed to go on loan to Everton, Fernando Torres remains hit and miss and is now injured, Samuel Eto'o is far from the player of his Barcelona and Inter Milan pomp. Demba Ba, meanwhile, simply hasn't convinced.
In the holding midfield roles, other than the energetic Ramires, no one has laid claim.
Frank Lampard is a club legend, but the first half against Spurs proved that sitting in midfield is far from his best position, while Jon Obi Mikel isn't positionally aware enough to play as a part of a double pivot—indeed, it's a stark contrast to when he plays as a sole holder in a 4-3-3.
As such, Mourinho has to find the correct balance, in terms of personnel, all across the park.
Who plays wide, who plays up front, who is his No. 10, who are his holders. Additionally, the Portuguese needs to find the right tactical setup—be it 4-2-3-1, 4-3-3 or another—to bring the best out of his individuals and quite simply to answer the question: What is Chelsea's best team?
They've made a decent start, but there are unquestionably improvements to be made.
