Manchester City are on the verge of sealing the £28million signing of Fiorentina star Stevan Jovetic. However, City suffered a setback in their pursuit of Alvaro Negredo after Sevilla president Jose Maria del Nido warned there is now only a ‘one per cent’ chance of a deal going through. New boss Manuel Pellegrini is anxious to sign the two strikers to fill the gaps left by the recent departures of Carlos Tevez and Mario Balotelli. City have been in talks with Fiorentina over Jovetic for some time, but it is understood the two clubs have finally agreed an initial fee of £23m that could rise by £5m in bonus payments. Fiorentina have previously stipulated that they would not sell the Montenegro international, 23, for less than the £28m buyout clause in his contract. City still hope to sign Negredo as well but have been unable to reach a compromise deal over the Spain striker amid concerns that Sevilla are trying to ramp up the price beyond £20m. Del Nido confirmed yesterday that the two clubs are some way apart in their valuations and said: ‘Either they pay what we ask or the player stays with Sevilla for another three years.’ Meanwhile, City are adamant that defender Aleksandar Kolarov will not be joining Juventus despite reports that they will listen to offers. The 27-year-old is believed to be open to a move after losing his place at left back to Gael Clichy, but with Maicon set to join Roma for £4m, City want to keep Kolarov and may add to their defence.
