Manchester City and Barcelona are vying for the signature of Fiorentina defender Juan Manuel Vargas, reports talkSPORT.
Reports in Italy had suggested that City were the clear favourites to land the Peruvian, and an alteration in the deal the Catalan giants are willing to offer has made them front runners to capture the 27-year-old.
Pep Guardiola's side are willing to offer forward Bojan Krkic as part of the deal to bring Vargas to the Nou Camp, hence putting themselves ahead of City in the race to sign him.
Despite Pablo Zabaleta and Aleksander Kolarov's decent form this season, Roberto Mancini is looking again for a suitable left-back to complete his back-four, and is again looking to his homeland.
The Eastlands club spent £17 million on bringing Kolarov from Lazio last summer, and after getting injury on his debut against Tottenham Hotspur, has flourished at full-back for City.
Zabaleta has been in and out of the City side ever since he joint in 2008, but when standing for the occasionally injured Kolarov, has been exemplary.
The Blues are still seeking for the right formula to mount a serious challenge for the Barclays Premier League and further investment, this summer, is expected as City look to close to the back to their neighbours Manchester United and Arsenal.
