Crystal Palace co-owner Steve Parish denies last summer's market approach was scattergun.
But he admits errors were made with former manager Ian Holloway.
"Last summer wasn't just thrown together," he told the Croydon Advertiser. "Ian and I and the people we were working with thought about every single player.
"Obviously Ian had a different style to Tony and so he brought in players who brought a different style.
"Some of them may not fit with us going forward but they are good players and the club will do OK out of those players, and those players will do OK having been at Crystal Palace and gaining the experience.
"And in there, there were one or two mistakes, but they weren't mistakes at the time. Some players didn't settle or maybe some didn't see eye-to-eye when they first arrived, for example.
"Sometimes it just doesn't work out for you at a club. "Maybe you don't take your chances or it just doesn't happen for you on the pitch.
"I am really comfortable with last summer. I think we'll look at less options this summer because Tony has got a much clearer idea of what he wants."
