Valencia were surprise winners at Chelsea on Matchday 1 and are in a three-way tie with their English opponents – and Ajax – ahead of the reverse fixture at Mestalla, where the English side have never lost.

• Valencia spoiled Frank Lampard’s European debut as Chelsea manager with a first victory against the Blues at the seventh attempt on Matchday 1. Rodrigo scored what proved to be the only goal of the game at Stamford Bridge, Chelsea’s Ross Barkley missing a late chance to equalise from the penalty spot.

• With Valencia, Chelsea and Ajax all on seven points in Group H, either Valencia or Chelsea will be through if they win due to their favourable head-to-head record in a potential three-way tie also involving the Dutch club.

Previous meetings
• All of the sides’ encounters before this season came in the space of four and a half years, four alone taking place in 2007.

• Chelsea also won 2-1 at Valencia in the following season’s group stage before a goalless draw in London. They went on to finish first in the section with Valencia fourth, and progressed all the way to that season’s final, losing to Manchester United – also in a shoot-out – in Moscow.

• Chelsea’s run to glory in the 2011/12 UEFA Champions League featured two games against Valencia in the group stage, Lampard scoring in a 1-1 draw at Mestalla on Matchday 2 before the English club won 3-0 at Stamford Bridge on Matchday 6, their sole home success against Valencia.

Form guide
• Valencia went down 3-0 at home to Ajax on Matchday 2, a second successive European defeat at Mestalla, and conceded a late equaliser to draw 1-1 at LOSC Lille in their third fixture before overturning a half-time deficit to beat the French side 4-1 last time out.
