The Magpies lost the game but Dubravka produced some vital saves for his team.
Patrick van Aanholt scored the winning goal for Palace in the first half and Lazaro was sent off for Newcastle in the second half.
Bruce has claimed that Dubravka is Newcastle’s best player and he was outstanding against the Eagles.
Speaking to the Chronicle, the Newcastle manager said: “The goalkeeper has made some great saves. Especially in the first half, that one from Gary Cahill. He’s arguably our best player and he will be disappointed when he sees the goal back.
