The in-form midfielder finished a fine move to open the scoring in Sunday’s fiercely-fought encounter that finished 1-1 at the Lane.
We went close on two more occasions as we had the better of the first half but Chelsea responded after the break and levelled through John Terry.
Fernando Torres’ red card saw us push Chelsea back again in the final 10 minutes and Gylfi was so close to a memorable winner, his volley dipping inches wide.
“It’s nice to get another goal, especially against Chelsea at home, but I would have preferred the three points,” said Gylfi, who admitted the overriding feeling was one of disappointment after such a good performance in the first half.
“We played well in the first half, created a lot of chances, got the goal but in the second half, Chelsea were on top until Torres was sent off.
“We then dominated the last 10 minutes but they defended well and we couldn’t get past them.
“We were on top in the first half and continued what we’ve been doing in the last few games. We’ve a lot of confidence and I think if we’d have scored the second goal it would have killed the game.
“Now we look to the next game.”
