Gary Neville has questioned the fragility of Chelsea's table-topping side when they are forced to use their squad players.
The Blues missed Marcos Alonso through illness in their 2-0 defeat by Manchester United and his absence seemed to severely unbalance the team.
Neville noted that all the main teams missed players but Chelsea failing to adjust without a left-back is a concern for Antonio Conte's side.
In his punditry role for Sky Neville said: 'If they'd have lost Hazard and Costa and come here to lose I'd say fair enough.
