The 23-year-old striker has been discussing his spell at Palace so far.
Indeed, the young striker knows he must look after himself more and avoid injury in south London.
And Wickham wants his goal against Watford during Sunday afternoon's FA Cup semi-final to be a kick-start to his Crystal Palace career.
The 23-year-old is quoted as saying by Sky Sports: "The manager's brought me in with a lot of expectation, which I know I've not lived up to, I've been injured a lot but before I had my last injury I was back scoring goals and that's what I love doing.
"I've got to look after myself, think about my training, my recovery, my preparation, make sure [an injury] doesn't happen again, because I've scored and hopefully it can be a kick-start."
Goals have been notoriously thin on the ground at Crystal Palace this season and the Eagles need Wickham to produce more big moments like he did at the weekend.
Emanuel Adebayor hasn't really worked out as a goalscorer - although Alan Pardew was probably always aware the experienced target man was more of a stop-gap signing.
The likes of Yannick Bolasie, Wilfried Zaha and Jason Puncheon are Palace's main threats but they can't carry the goalscoring burden all by themselves. They are the type of players who will thrive off a clinical front man who leads the line effectively.
