Obafemi Martins is attracting interest from Premiership clubs, according to the Internazionale striker's agent.
Inter's acquisition of Hernan Crespo and potential moves for Juventus striker Zlatan Ibrahimovic and Fiorentina's Luca Toni have prompted Martins to consider leaving the San Siro.
The Nigerian's agent Patrick Bastianelli told the Gazzetta dello Sport: 'He has offers from Tottenham, Newcastle, Portsmouth and Valencia.
'He is very tied to the (Inter) president Massimo Moratti and the club. But it is clear that if another attacker comes after Crespo, then we will have to talk to Inter, even if at the moment Martins is not on the market.'
Martins, 21, has scored nine goals in 28 Serie A games for the Nerazzurri.
