The Premier League giants are in the market for a striker ahead of the next summer transfer window.
Harry Kane and Victor Osimhen are two of their top targets and they are also reportedly considering making an offer for Randal Kolo Muani.
Manchester United also have their eyes on Ramos and the club have been keeping tabs on the Benfica hitman this summer.
And it has been claimed that the club are planning to table an opening offer for the 21-year-old striker in the next transfer window.
Ramos has scored 24 times in 36 appearances for Benfica this season and he has a contract until 2026.
He is likely to cost around £70m if someone wants to sign him in the summer and it is unclear whether Manchester United want to spend such big figures for Ramos.
But they are likely to test the waters and put in an opening bid for him in the summer transfer window.
Erik ten Hag wants a new striker next season and Ramos is one of several players Manchester United are looking at.
