Head coach Unai Emery said after that match that the club is likely to sell a couple of players this week as they look to trim the squad.
West Ham also made an offer worth around €30 million to sign Maxi Gomez but are now ready to turn their attention to Lucas after Celta Vigo asked €40m for the Uruguay worldwide.
Capped 88 times by Colombia, Sanchez would add experience to a position where West Ham do not have depth.
"There are other clubs interested but joining West Ham would allow him to continue in London and in the Premier League and Lucas wants to continue in London".
It's understood the club are in talks to bring in Colombia global Carlos Sanchez.
Alfredo Pedulla claims the Florence outfit are keen on signing the 22-year-old on loan with an option to purchase, with West Ham considering cashing in as Fernandes has fallen down the pecking order following the recent acquisitions.
Sanchez's future appears to be away from Fiorentina after spending last season on loan at La Liga side Espanyol.
He has Premier League experience having spent a two-year spell at Aston Villa, leaving in 2016.
"Listen, it's great first and foremost to come back and see them, but I'm a West Ham player".
