Antonio Conte wants Tottenham to spend big again in the winter window in a bid to further reinforce their squad.
However, the north London club are unlikely to throw big money around in January and the budget is likely to be limited.
Conte wants to bring in a new right-back in the January window and Porro has been the club’s top target.
But it has been claimed that it seems unlikely that the club will be able to sign the Portuguese in the winter window.
The 23-year-old is a key player for Sporting Lisbon and they do not want to lose him in the middle of the season.
The Portuguese giants are not likely to make any efforts to make it a plausible deal for Tottenham to do in January.
Tottenham could be forced to look for a cheaper option in England if they are to sign a new right-back.
