Chelsea warned they cannot sustain season with Xabi Alonso's open defence

Former Chelsea defender Frank Leboeuf has warned that Xabi Alonso’s side cannot sustain a full season playing the way they currently are defensively.

The Blues have looked vulnerable at the back under Alonso, with the former Real Madrid manager opting to use a back three since taking charge.

Leboeuf believes Chelsea’s defensive structure needs to change, particularly with Wesley Fofana struggling to look comfortable in the system.
