Everton had a ‘spy’ at the match between Benfica and Famalicao on Saturday, reports Record.
They weren’t there alone, with the game attracting a large number of scouts from clubs outside of Portugal, all planning for signings ahead of future transfer windows.
Along with Everton were officials from Manchester United, Atletico Madrid, Nice, Toulouse, Real Sociedad, Villarreal, Sevilla, Valencia, Sheffield Wednesday and Blackburn Rovers.
Benfica won the match 4-0, with 30 year old Pizzi their Man of the Match. He scored two of the goals and assisted another from his role on the right of midfield.
Tavares looks a reasonable target for Everton, depending on what the club plan to do with their right-back position. Any move would be more likely in the summer rather than the January transfer window.
