Spurs are now said to be one of the teams taking a keen interest in the situation, with Martins potentially an option for them.
And if Tottenham did manage to pick up Martins on a free transfer then it would surely be a the deal of the summer.
Martins has developed a reputation as one of Europe’s most exciting young attackers after his performances for Sporting this season.
The 23-year-old has scored 13 goals and claimed 13 assists across all competitions this past campaign, with his pace making him a huge threat to defences.
Martins has been tipped to leave Sporting for huge money, but all of a sudden it appears he could be the biggest bargain on the market, if he leaves the Portuguese club on a free.
And if Spurs could complete the deal to bring in the brilliant wide-man, then it would surely be the finest piece of transfer business done by any club this summer.
