Sunderland striker Wickham is well aware of the quality Zaha possesses and has tipped him to be one of the Young Lions' best players throughout the competition.
"He is going to be on a massive high," Wickham told the Football Association's official website.
"He has done really well with what he has achieved this season, and he can only make the team stronger."
Of the team's chances, Wickham added: "We have strength in numbers in every position. On our day I think we can beat anybody.
"The week in Turkey prepared us physically for the weather. The vibe in the camp is good and we're looking forward to Wednesday night.
"We've had the coaching staff drum into us the importance of the tournament and I don't think anyone has any doubts in the team that we can't do well."
