Former Tottenham trialist Bruno Uvini is set for a new challenge in Portugal.
The centre-back is a former Brazil under-20 captain, and is under contract with Napoli where he moved after his switch to Spurs fell through.
He has failed to earn a regular place at the Serie A side, sent out on loan to Serie B side Siena and then back to Santos in Brazil.
Italian website Tuttomercatoweb report that Uvini is close to signing in Portugal, with a €2.7 million fee agreed between the two sides.
Uvini is still only 23-years-old and has plenty of time to get his career back on track. The defender's performances for Santos in Brazil were well received, and Portugal's Primeira Liga is regarded as a strong developmental league for players to develop.
Sporting are set to finish in third place and go into the Champions League qualifiers next season. Napoli are three points off a qualifying place with one game to go in Italy.
