Tottenham Hotspur appear to be gathering further information on Sporting Lisbon right-back Pedro Porro ahead of a potential move.

The Lowdown: Spurs preparing Porro bid

Fabio Paratici and Daniel Levy appear to be making plans to bolster Antonio Conte’s squad in the January transfer window, with Spurs still competing in three competitions.

Recent reports have suggested that the north London club are preparing a £39m bid for Porro, previously of Manchester City.

The Premier League champions sold the 23-year-old in the summer, and it looks as if Tottenham have been in contact with former club officials from the Etihad Stadium.

The Latest: Spurs want more information

Sport Witness relayed an update from O Jogo on Saturday regarding Porro and Tottenham.

They claimed that Spurs chiefs have doubts about the player’s ‘physical condition’ and have contacted ‘former Manchester City officials’ to get a ‘more informed opinion’ on the defender.

The Verdict: Smart thinking

With Spurs reportedly weighing up a £39m offer, it is vital that club officials are completely sold on all aspects of the player, with his physical condition being crucial.

Lauded as a 'special talent' by journalist Zach Lowy, Porro has missed numerous matches in recent years due to various knocks and muscle injuries, so it is a smart idea for Tottenham chiefs to contact former City officials on the player before committing to a potentially risky transfer.

The Manchester club might not be too helpful, though, considering that Porro never made a first-team appearance at the Etihad and spent the majority of his time on the club's books out on loan with Real Valladolid and his current employers Sporting.
