Chelsea have reportedly stepped up their interest in Slovakian international midfielder Marek Hamsik.
TalkSPORT reports that the Stamford Bridge outfit sent scouts to watch the 23-year-old in the recent Serie 'A' clash between Napoli an AC Milan, with Hamsik's Partenopei side on the end of a 3-0 defeat in-front of the watching Chelsea contingent.
It's not the first time the Blues have been to watch the player first hand, and latest reports in the Italian press claim Chelsea have made contact with the player's representative as Carlo Ancelotti looks to engineer a move to west London.
Manchester United have also been keeping tabs on the player, with Sir Alex Ferguson thought to be keen on the attacking midfielder.
The Red Devils were linked with a move as recently as the summer, and Corriere dello Sport now claim that Manchester United scouts were also in the stands for the match last night.
Barcelona are also reportedly interested in the Slovakian international, who joined Napoli in 2007 after three seasons with Brescia.
A €35 million club valuation is thought to be a potential stumbling block for all suitors, although Chelsea proved in January that they are still willing to spend big to bring players to the club.
Ferguson is also thought to have money at his disposal at Manchester United, although the Scot would be keen to negotiate a smaller fee for the player's services.
