Leeds United continued their unbeaten start to the Premier League season as the two sides played out a 0-0 draw at Elland Road.
Things could have been very different, however. Palace favourite Tyrick Mitchell had a second-half goal disallowed for offside against Anan Khalaili following a VAR review.
It was a fairly even match, but Palace boss Sage believes his side could have easily returned to South London with all three points.
Speaking to Sky Sports after the game, he said: "We worked a lot during the last week. We conceded less chances than before, but we conceded one big one and our goalkeeper made a big save so we have to congratulate Walter Benitez on that.
"We deserved something else than a draw and we created some chances without scoring. We played well today, we created a lot. It's easy to make it one time (a good performance), so we have to do it every game and we need to perform better to take points."
