Edin Dzeko's former Zeljeznicar boss Amar Osim says Manchester City will only get better.
Dzeko was named Premier League Player of the Month for August.
Osim, who threw Dzeko into the Zeljeznicar first team at 17 in 2003, believes that the striker is only going to get better.
He told the Manchester Evening News: "It was always going to take time.
"Dzeko is a player who depends on those around him, so he needed time to adjust.
"He's not an individual player who will dribble past five players like Lionel Messi. He is a team player.
"Roberto Mancini always knew what Dzeko was capable of, and the fans are starting to see that now as well."
