Manchester United are scouting Benfica pair Goncalo Ramos and Odiessas Vlachodimos.
The Manchester Evening News says United are eyeing both Benfica stars as they seek to strengthen two key positions.
United see Ramos as a key centre-forward target, while Vlachodimos is viewed as a cover for David de Gea.
The Greece international has been on United's radar for at least two years and would arrive as Dean Henderson is sold to Nottingham Forest. He has a deal to 2024.
Ramos, meanwhile, is considered alongside Harry Kane (Tottenham) and Victor Osimhen (Napoli), but can leave Benfica for a more affordable price.
