Chelsea have remained unbeaten against Barcelona as Lionel Messi scored an equaliser to deny the Blues famous victory in the first leg of their last-16 Champions League tie at Stamford Bridge.
Willian, who had twice hit the post in the first half, put the Blues ahead with another low strike from outside the penalty area.
However, Antonio Conte’s side were only ahead for 13 minutes before Andreas Christensen played a loose pass and Andres Iniesta linked up with Messi, who slotted it past Thibaut Courtois.
The second leg takes place at the Nou Camp on Wednesday, 14 March and La Liga leaders Barcelona, with the benefit of an away goal, will be favourites to advance.
The result at Stamford Bridge does mean that none of the English teams have lost in their last-16 first-leg ties so far.
Liverpool beat Porto 5-0, Manchester City defeated Basel 4-0, Tottenham drew 2-2 at Juventus and Manchester United play away at Sevilla on Wednesday, 21 February.
