Antonio Conte has told his players that they must be prepared to 'suffer' if they're to progress past Barcelona into the quarter finals of the Champions League on Wednesday.
Ernesto Valverde's men take a slim advantage back to the Camp Nou, having scored an away goal in their 1-1 draw at Stamford Bridge in the first leg, but the Catalans will be on guard after Willian cracked the post against them twice in west London.
Having cruised through most of Saturday's 2-1 win over Crystal Palace - only for the introduction of Wilfried Zaha to help the south Londoners give Conte and co a massive scare late on - the Blues should be reasonably well-rested for Wednesday's game.
