Manchester City will step up their interest in Maicon, the Internazionale defender, before the transfer window closes with Roberto Mancini keen to recruit the Brazilian to strengthen his defensive options. The player has a year remaining on his contract and Inter would consider an offer in the region of €6m (£4.7m).

Mancini is an admirer of the 31-year-old having worked with him at Inter for two seasons before the Italian left the club in 2008. Maicon, who can play right-back or further forward and has won 66 caps for Brazil, would provide competition for Pablo Zabaleta, the current first-choice right-back. He would also be at ease with Mancini's move to play 3-5-2 in some matches, with many Serie A sides now lining up in that formation.

Mancini's other option at right-back, Micah Richards, is unavailable until after the international break because of an ankle injury, having been out of first-team favour since City's successful title run-in last season.

Last week Maicon's agent, Roberto Calenda, confirmed Mancini's interest. He said: "There is interest from Manchester City, Real Madrid and Chelsea in the player. There is no possibility that he goes to Milan or Juventus. He has worn the Nerazzurri shirt for six seasons and has too much respect for the fans to betray them in that manner. He could also yet remain at Inter."

Roberto Di Matteo has since bought the right-back César Azpilicueta from Marseille to Chelsea for around £7m, which increases the prospect of City taking Maicon to the Etihad Stadium.

The champions are also in talks with Fiorentina for their 19-year-old Serbian central defender, Matija Nastasic. The proposed deal is thought to be costing City £12m plus Nastasic's countryman Stefan Savic, who would move to Florence as part of the transfer. Nastastic has played twice for Serbia and made just 26 appearances for Fiorentina, having moved there a year ago from Partizan.

City are still pursuing Scott Sinclair despite Swansea City's turning down their £6.2m offer and may move to lodge an official bid for Theo Walcott, after he rejected Arsenal's £75,000 a-week new contract offer, Edin Dzeko and Nigel de Jong may now remain at the club.

City's inability to sign Robin van Persie, who moved instead to Manchester United, means there is less chance that Dzeko will be moved on though as with De Jong if the club receive an attractive offer before the window closes on Friday evening it would be considered.

Jack Rodwell, Mancini's sole summer buy so far, has been called up by Stuart Pearce for the England under-21 matches against Azerbaijan and Norway next month.
