Under the microscope today is Juventus winger Milos Krasic, who is reportedly a January target for both Chelsea and Tottenham.
Krasic has found himself on the peripheries at the Juventus Stadium ever since Antonio Conte was appointed manager in May, and has been frequently linked with a move away from Turin.
Stamford Bridge and White Hart Lane have been touted as potential destinations for the 27-year-old Serb, but what would he offer Andre Villas-Boas or Harry Redknapp?
One clear positive for Chelsea or Spurs regarding the acquisition of Krasic would be the financial aspect, with the midfielder said to be available on loan.
This would give Villas-Boas or Redknapp the opportunity to run the rule over Krasic in the short-term, before deciding whether or not make a permanent summer swoop.
For Chelsea in particular, Krasic would also be able to provide some natural width to their midfield which, at times, has been particularly narrow this season.
Alternatively, he could operate either side of the main striker - likely to be Fernando Torres - in a 4-3-3 formation, and would provide a goalscoring option going forward.
Spurs, meanwhile, are already blessed with the likes of Gareth Bale and Aaron Lennon for their wide midfield positions, so Krasic would be able to provide Redknapp with extra cover.
He can, though, work through the middle when required, which would relieve the creative burden on the likes of Rafael van der Vaart and Luka Modric.
A lack of match practice could prove to be a particular sticking point with Krasic, who has not played a competitive game since October 22.
He has also made only eight appearances this season and it is likely he would take some time to adjust to the rigours of the Barclays Premier League.
His attitude may also be considered an issue, with some reports suggesting a rift with Juve boss Antonio Conte to blame for his lack of involvement this term.
It is rare that a player of Krasic's quality and experience - both at club and international level - can become available like this halfway through a season.
Hence, he would certainly prove to be a valuable signing - albeit only temporarily - for either Chelsea or Spurs, should they be able to complete a deal.
However, the fact that he is eligible for the Champions League, and has played in the competition numerous times in the past, would mean he may be a better fit at Stamford Bridge.
