Tottenham are unhappy with the asking price Sporting CP are demanding for Pedro Porro.

The Spain fullback is a January target for Spurs.

But Italian transfer expert Fabrizio Romano said, "Pedro Porro is at the top of Tottenham's list for a new right-back.

"Spurs will try to sign the player and he is interested in a transfer.

"A deal in January will be difficult because Sporting has been very clear: they pay €45m from termination clause or nothing done."
