Tottenham Hotspur's proposed deal for the Sporting CP right wing-back, Pedro Porro, has hit the rocks with just hours before the transfer deadline.

What's the latest?

On Saturday night, Fabrizio Romano reported the deal to bring Porro to north London had been agreed upon and the player would be heading for London following their game against Porto.

However, on Monday morning, David Ornstein broke the news that the proposed deal had hit an issue as Sporting reneged on the details of the deal.

The report suggests the player has been left distraught having been told by the club's president he would be allowed to leave following their League Cup final on Saturday.

And speaking on Sunday night via his YouTube channel, journalist Alasdair Gold suggested if this deal was to hit the rocks - as it has done - it may take the player to cause an issue with Sporting to see it go through:

"Obviously, we know Porro wants to come and I do wonder if Sporting do make it difficult in the final stages whether he then has a problem with that because he does seem from everything I've heard to be quite keen to make the move."

Late frustration

This is a deal which has been in the offing since the beginning of the January transfer window with the north London side having identified Porro as their main target.

Talks have proceeded since the early stages of the window with reports suggesting Sporting were intent on Spurs coughing up the player's £39m release clause if they were to sign him.

Nevertheless, Spurs continued to negotiate and it was believed on Saturday night the two clubs had agreed on a deal which would see Spurs pay a fee close to the release clause.

And yet, with hours to go, it seems as if Sporting are now wanting more money for the deal with Gary Jacob suggesting the Portuguese side wants a further £2.6m out of Spurs.

With this in mind, we do wonder whether the player could be forced to kick up a stink in Portugal in an attempt to force through a move late on in the window.

This is a deal which Spurs have spent the entire month working on and it appears the player is desperate to make the move to north London.

We have already seen the likes of Leandro Trossard cause an issue over his future before making his move and although it is not always pretty, it can often be effective.
