Chelsea opened their account at the Mestalla in the 56th minute through a Frank Lampard strike but a penalty from Roberto Soldado in the closing stages of the game saw the home side walk away with a share of the points.
Speaking to the press after the game, Emery commented: “I'm very happy with how the game went and with the attitude of my players, especially as we were up against a great team.
“A draw was a fair result, even more so when you consider the fine performance of our goalkeeper Diego Alves balancing out the good chances we created.
“We are happy with a point. However, we will have to improve in front of goal to pick up all three in future.”
Valencia face German club Bayer Leverkusen in their next Champions League clash on October 19.
