Former Manchester City defender Danny Mills has claimed that the Citizens will struggle this season, finishing as low as fourth in the Premier League.
Manuel Pellegrini's side finished second in the league last season, but they have made a good start to their current campaign, thrashing West Bromwich Albion 3-0.
Mills, however, told BBC Sport: "Joe Hart and Sergio Aguero are the only big players who have performed. Aguero is key and is injury prone. Can Wilfried Bony come in and be that player?
"If Aguero goes missing then City might struggle. I've tipped them to finish fourth."
Mills played for Man City between 2004 and 2009.
