Manchester United and Liverpool could face stiff competition for the services of Jackson Martinez after Galatasaray became the latest club linked with a bid for the Porto striker.
The big-spending Turkish giants are ready to open the bidding for the Colombian at £37.5m, according to Portuguese newspaper O Jogo.
Martinez's price tag is expected to rise even higher, with Russian outfit Anzhi Makhachkala also said to be considering tabling on offer.
The forward has scored 23 goals in 25 league appearances for Porto this season after joining the club from Mexican club Jaguares last summer.
