Since moving to the Gunners for £72 million in the summer, Pepe has struggled to impose himself in Unai Emery’s starting XI, having scored only one competitive goal two months into the new season.
Zaha, who was linked with a move to the Emirates Stadium himself over the course of the latest transfer window, has every confidence that his compatriot will prove to be a star in north London.
“I have got nothing but faith in him, I’ve got confidence that he will produce the same thing that he did before because we both play for Ivory Coast and I’ve seen the talent he’s got, but not everyone sees it,” the Crystal Palace winger told BBC Africa.
“I see the social media, I see everything and it’s a thing where he needs time,” the former Manchester United man said.
“He’s come from another league, he’s young.
“There’s this price tag that he has not put on himself, people have put that on him because of his performances, so you’ve got to give him time for him to reproduce that, it’s not going to come like that.”
Pepe has made eight appearances for Emery’s side so far this season, with his only goal coming in the 3-2 victory over Aston Villa.
However, he showed positive signs against Bournemouth in the 1-0 win immediately prior to the international break, setting up David Luiz from a corner to grab the eventual winner.
When he returns, his first challenge with Arsenal, who lie third in the Premier League, will be an away trip to Sheffield United on Monday, October 21.
