Chelsea will not know their Champions League fate until the final group games after they drew at Valencia in an incident-packed match. The Blues looked set for a place in the last 16 after Christian Pulisic gave them a second-half lead and Kepa Arrizabalaga saved Daniel Parejo''s penalty. But with eight minutes remaining, Daniel Wass'' intended cross from the right bamboozled Kepa, who appeared to misjudge its flight. Maxi Gomez had missed two opportunities from close range for the home side before Carlos Soler gave the Spanish club a 40th-minute lead when he converted Rodrigo Moreno''s cross. However, Chelsea equalised 108 seconds later as Mateo Kovacic turned at the edge of the area and struck a low effort into Jasper Cillessen''s right-hand corner. &#9726:Chelsea striker Abraham carried away on stretcher The match was turned on its head in the 50th minute. when Pulisic fired in. His strike was flagged offside and looked so to the naked eye, but after a three-minute deliberation by the video assistant referee (VAR), the goal was given with replays showing Ezequiel Garay''s boot played the Chelsea man on. The next big moment in the match came in the 63rd minute when Valencia won a penalty following Jorginho''s foul on Jose Gaya. But after a brief VAR check, Parejo spot-kick was brilliantly pushed away by Kepa. Valencia, who created several clear-cut opportunities during the match, then spoilt Chelsea''s night when Dane Wass fortuitously found the net with his deep cross. Blues defender Kurt Zouma had a header cleared off the line and Moreno missed at the far post in a breathless finale to the contest. Chelsea may have to defeat Lille in the final match to secure a place in the knockout round, with Ajax, who beat the French side 2-0, and Valencia still in the mix. Late equaliser and Abraham injury dampen Chelsea''s day Chelsea might feel aggrieved and relieved about the result. Some might criticise Frank Lampard''s team for not playing more defensively after taking the lead, but this season''s Blues have often thrown caution to the wind. Kovacic and Pulisic were his standout players. Croat Kovacic produced yet another workhorse-like display in midfield and ended a run of 122 games without a goal when he drilled home from the edge of the area. The ex-Real Madrid man should have another moments after the restart, but failed to produce enough of an angle on his shot. That attempt was set up by Pulisic''s superb mazy run. The American has had a dream start to his new career with the Blues and - when it was eventually given - celebrated his fifth goal in eight away appearances. Aside from the late equaliser, the only other negative for Chelsea was striker Tammy Abraham''s injury towards the end of the first half, when he was helped off the pitch after landing awkwardly following an aerial challenge. Valencia wasteful at Mestalla Valencia coach Albert Celades might get his forwards to attend early training on Thursday for some extra shooting practice. Former West Ham target Gomez missed two simple chances from close range, Rodrigo failed to find the target with his chip when Kepa was stranded, Parejo missed a penalty before Rodrigo shot wide at the far post in the final few seconds. The Spanish side had 18 shots in total. Soler showed the others how it should be done with his coolly slotted finish: Wass'' equaliser was one of the home side''s few moments of good fortune in attack.
