Four draws from their last five games have hurt Arsenal's hopes of surpassing Manchester United and some supporters have expressed their frustration with Wenger as they near the end of what would be a sixth successive season without a trophy.
Coyle said: "They're six points behind Manchester United with Manchester United still to play. Arsenal have shown before that they'll be in the mix and I've got no doubts they've got a fantastic chance of winning the league.
"If I wasn't a football manager and someone said who would you go and watch, I would watch Arsenal every week because I love the way they play and the quality of the players they have.
"Arsene Wenger is, always has been and always will be a truly outstanding manager, one of the best managers in world football.
"We've had our arguments along the way but that goes without saying because he's passionate about his team and I am about mine, but you can never doubt the quality of Arsene Wenger as a manager and the teams he's built after he's lost big players year in and year out."
