Crystal Palace progressed into the fourth round of the FA Cup after a 2-1 win at local rivals Millwall.
Patrick Vieira fielded a strong side despite missing Wilfried Zaha, Cheikhou Kouyate and Jordan Ayew, who were on international duty at the Africa Cup of Nations.
Palace went behind after 17 minutes after a howler by keeper Jack Butland who dallied with a pass back and kicked the ball straight to Benik Afobe who scored into an empty net.
Michael Olise got Palace back on terms just seconds after the restart with a fine curling strike in off the post.
And the £8m summer signing from Reading crossed for on-loan striker Jean-Philippe Mateta to head home what proved to be the winner in the 58th minute.
