Inter midfielder Joao Mario has reportedly turned down a move to the Premier League after rebuffing Watford's advances.
The Portuguese international has been linked with Manchester United in recent times after rumours surfaced of a potential swap deal involving United misfit Henrikh Mkhitaryan.
Silva, who enjoyed his greatest success to date whilst in charge of Greek giants Olympiacos, managed Joao Mario for a season during his time at Sporting CP and is reportedly keen to strengthen his midfield options after a poor run of form.

Joao Mario meanwhile, who signed for Inter in a whopping €40m deal in 2016, is also understood to be on the radar of five-time Europa League winners Sevilla, with a move to Los Rojiblancos said to be more favourable for a player looking to establish himself on the European stage.
Inter are understood to be reluctant to part with the player, but may look to strike a deal with the La Liga outfit as they continue to monitor Joaquin Correa. The 23-year old Argentine has struggled for minutes in Spain this season, with reports suggesting that a player plus cash deal may be offered to the Nerazzurri in attempt to prize Joao Mario away.
The 24-year old has 31 international caps to his name for Portugal, having represented the Euro 2016 winners at every youth level available.
