Daniel Wass scored a fortuitous and crucial late equaliser for Valencia to secure a 2-2 draw at home to Chelsea on Wednesday in a thrilling contest that left Champions League Group H wide open.

Frank Lampard's men had looked on course to leave Mestalla with the victory that would have clinched their spot in the knockout phase after Christian Pulisic's go-ahead strike was added to by a Kepa Arrizabalaga penalty save, but Wass' effort led to a share of the spoils.

A dramatic, end-to-end first half saw both sides threaten regularly and, despite some wretched finishing, two goals in as many minutes from Carlos Soler and Mateo Kovacic – his first for Chelsea – meant the score was level at the interval.

Everything looked to be going Chelsea's way after Pulisic struck and Kepa parried Dani Parejo's penalty, but Wass' right-wing cross rather fortunately went straight in with eight minutes left to rescue Valencia, who would have won it but for an inexcusable stoppage-time miss by Rodrigo.
