The striker says they are determined to finish as high as possible after a strong start to the season.
Pardew is enjoying something of a renaissance at Selhurst Park, having taken the managerial reins last season following his exit from Newcastle United.
He led them to a tenth placed finish last season, and they have been highly impressive this season, currently sitting in sixth spot in the Premier League table and just two points outside of the top four.
And Wickham has hailed his manager, saying that other players also gave him positive reviews when he sought their opinions before joining the Eagles.
"He's fantastic. I spoke to him a couple of days before I signed and that was what sold it,” he told cpfc.co.uk.
"He gave me a feeling that managers that I've had before haven't really, it was confidence and that's what every footballer feeds off. I spoke to a few players from this club and ones that he'd worked with before and they all told me good things, so it was kind of a no-brainer.”
The striker was also adamant that he and the rest of the squad are determined to finish as high up the table as possible.
There is plenty of optimism around the club after the top-half finish last year, while their current standing has them dreaming of going even higher this season.
The addition of Yohan Cabaye over the summer was another indication of the ambition being shown at Selhurt Park, and following their strong start, Wickham says the aim is to keep that going and not just settle for a middle-of-the-road campaign.
"The manager said to us at the start what the aim was: we want to push up as high as we can, we don't want to settle for mid-table," he added.
“We don't want to just finish ninth, tenth, eleventh, we have ambitions of eighth and above. That's what we have to work for. I feel very confident in this team, the boys are confident in themselves, we're happy, there's a real buzz.”
