The Spanish 'keeper not only kept a much deserved clean sheet but also pulled off a remarkable save to keep the visiting Bluebirds from taking a point from under the noses of Palace.
His heroics earned him the Man of the Match award as he won 43.3% of votes from Palace fans, beating Cheikhou Kouyate to first place.
The match was only Guaita's third league game of the season and Palace have kept two home clean sheets from those fixtures, conceding only twice in the win over Manchester City.
