Mauricio Pochettino was quick to admit that his side 'can't afford' shock defeats like their loss to Middlesbrough in midweek, as he spoke to the media ahead of Saturday's west London derby.
The Blues were handed a chastening first leg defeat to Boro after a Hayden Hackney goal in the first half was enough to secure Michael Carrick's side the advantage heading into the second meeting.
Chelsea have found consistency and form hard to come by throughout the season, and the midweek loss was just the latest result to spark criticism of Pochettino's side.
