Alan Pardew feels that the squad is in a much better place now, fitness-wise, compared to the start of the season, as Palace prepare to host AFC Bournemouth at Selhurst Park on Saturday afternoon.
Speaking during his pre-match press conference, the manager said he felt the fitness levels had improved, with those players who had come back later from the summer break now up to speed.
"We are much better in the squad, in terms of the players we've got available and with game time [under their belts] as well," he said. "Our boys who played in the Euros are all up to speed now."
Asked whether it was a must-win game for the Eagles, given the winless start to the new campaign, Pardew replied: "No, I think it's an important game though, for both clubs, because we don't want to be rooted at the bottom with zero points after three games.
"We are going through changes to the team, to the squad, because we want to put right the second half of our last year and we're in the process of doing that. A little bit slower than I would like, but that's the market I'm afraid.
"We're making changes to try to take the team in a different direction and there was a little bit of that on Tuesday night [against Blackpool], I think you could see that, and I'm hoping to see a little bit more on Saturday. We're never going to be completely nailed down at this stage, but there are signs. And I'm hoping that our fans see that on Saturday.
"Our fans have been terrific," he added. "They understand what I'm trying to do and what we're trying to do as a club. You can't play the way we play for the next 5 or 6 years here, we have to evolve. This is going to be a season of evolution."
