The Gabon international is out of contract at the end of next season and reports have claimed he could leave the club.
"It is very important that they keep him because there are not many players in the market who can score 25 goals a season. It's a massive thing to keep him and fight for the league in future seasons."
He added: "There are many points still to play for until the end of the season.
"It's not easy because the position right now is not the best but with the many, many points left there is a possibility of top four for sure. I believe they can make it. Why not?"
