Mancini has put the blame on director of football, Brian Marwood.

City has been linked with the likes of Liverpool defender Daniel Agger, Roma star Daniele de Rossi and Arsenal striker Robin van Persie this summer.

"After four months, I don't know what to say. You need to ask Brian Marwood," said Mancini.

"I am not the sporting director. I can't say anything about players."

Marwood determines the overall policy at the club.

When asked about the management structure at City, Mancini replied: "I am not happy - but I don't know what to say."
