Manchester City boss Roberto Mancini is hopeful a deal to sign Arsenal midfielder Samir Nasri can be tied up "very quickly".
With discussions between the two clubs believed to have been going on for some time, it had been expected Nasri might be confirmed as a City player this week although no such announcement has yet been made.
"I hope we can close it very quickly now, but I don't know the last news about him because my concentration is on the game," Mancini said. "But I hope - also because the market finishes in the next 10 days."
Asked why there may have been a delay in proceedings, Mancini said: "I don't know - this is not my job.
"I don't know why, but it is probably because Nasri is a good player, or because there is some problem."
In terms of potential outgoing personnel, one player who seems certain to leave City is Emmanuel Adebayor.
Spurs boss Harry Redknapp this week revealed Spurs were in talks with the Blues about a move for the striker, although Mancini would only say it was "possible" Adebayor was about to be sold.
