Palace boss Ian Holloway was “delighted” with the application of his players in the 2-1 win over Dagenham and Redbridge.
Holloway made 11 substitutions at half time as the Eagles fielded 23 different players on Saturday afternoon, but the gaffer was pleased with the way the players gelled on the pitch.
He said: “I'm delighted with the lads' attitude. We looked professional, we put a bunch of strangers in there really, with a lot of our young kids, but I thought we did really well.
“It was very tough. It's aways great to get that first game under your belt. As a player, anyone will tell you when it's hot you feel like you've got no legs, like you're not sharp enough.
“Luckily we've come through it and we're delighted with the way Dagenham played. They played the game properly, they made tackled but they were fair and we tried to do the same.”
Quincy Owusu-Abeyie, Elliot Grandin and Atdhe Nuhiu, who opened the scoring for Palace in the first half, all played 45 minutes in a bid to earn a contract at Selhurst Park.
But Holloway said that he will try and look at the trio of trialists again before deciding whether or not to offer them a permanent deal.
“I'll use some of them again on Tuesday if their agents will let me. That's the first game and you should never judge anyone on their first game. They've bedded in with us and I quite like them as people, so we'll have some tough decisions to make.”
Owen Garvan, scorer of the Eagles' second from the penalty spot, was forced off late on in the match, but Holloway confirmed that the injury was nothing serious.
He said: “He's just got a sore knee. He's got patella tendonitis which isn't very nice. He knows how to manage it, but when the pitch is hard, we're not used to that and that caused him a problem.”
Garvan should be fit to take his place in the squad for Palace's next pre-season game at Gillingham on Tuesday night.
