Crystal Palace winger Wilfried Zaha said he was "lost for words" after Yoane Wissa cancelled out the Ivorian's sensational second-half strike to deny the Eagles victory.
Fit-again Zaha had given Palace the lead with a sumptuous effort into the far corner after collecting a Cheick Doucoure pass on the edge of the penalty area.
"Just one lapse in concentration ruins all the hard work," the forward told BT Sport.
"We literally just had to keep it tight. As soon as we went into the lead, we just started to defend. I don't see why we do that.
