The former Newcastle United forward is surprised the reigning Premier League champions haven't used their January signing more.
The forward joined City from Premier League side Swansea City during the January transfer window but had to wait for his debut as he was away with the Ivory Coast at the Africa Cup of Nations.
It then took six games for the forward to score his first goal for the club, which came in the 3-0 win over West Bromwich Albion on Saturday afternoon, although his game time has so far been limited by manager Manuel Pellegrini.
Now, Shearer has said that he was surprised by the reigning champions’ decision to hold the forward back.
"I was surprised Bony wasn't in the team earlier,” said Shearer on Match of the Day 2 Extra.
“He showed yesterday what he can give them going forward.”
The former player turned pundit has also criticised Bony’s teammates Stevan Jovetic and Edin Dzeko for their lack of goals this season, despite the quality of the City squad around them.
The duo have just a handful of goals between them, leaving the goal scoring burden to star man Sergio Aguero, and as far as Shearer is concerned, that is not good enough. On the other hand, he is convinced that Bony will prove to be a big addition for Pellegrini’s side, despite having to wait so long for his first goal for the club.
"I think Wilfried Bony will be a big addition for Man City,” added Shearer.
“When you look at Edin Dzeko and Stevan Jovetic, with only five or six goals each, to be playing in a team that creates that many chances and score so few goals is not good enough.”
