Manchester United are reportedly pursuing Chelsea and Arsenal target Stevan Jovetic.
According to talkSPORT, the Barclays Premier League champions have joined two of their closet rivals in the race for the Fiorentina winger, who has been stalling over extending his stay in Florence.
Chelsea and Arsenal have been linked with Jovetic for a number of months but, with United also said to be on his tail, the Viola are ready to offer him a bumper new deal.
However, the 21-year-old's agent says a contract renewal will depend on 'many factors'.
"He has another two-years on his contract with Fiorentina, but his renewal depends not only on our will, but on many factors," Fali Ramadan told with firenzeviola.it .
"I haven't yet spoken with Fiorentina, though I expect to do so shortly."
Liverpool are also reported to have been monitoring the Montenegrin but, after Kenny Dalglish added Stewart Downing to his ranks in the summer, the Reds are not expected to follow up their interest.
United, meanwhile, brought Ashley Young to Old Trafford during the transfer window, but Sir Alex Ferguson is alleged to be keen to add further width to his squad.
Arsenal, though, are more in need of long-term midfield reinforcements after the departures of Cesc Fabregas and Samir Nasir prior to the transfer deadline.
Arsene Wenger did acquire Mikel Arteta and Yossi Benayoun before the end of the summer, but the Arsenal boss is likely to dip back into the transfer market again in January.
