The LaLiga side have made the 24-year-old France international their priority when the transfer window reopens, but if they cannot reach a full agreement to sign him they will begin to look elsewhere.The alternative options? Manchester City strikers Erling Haaland and Julián Álvarez.Alvarez, the 23-year-old Argentina international, is the latest star on the radar. While Los Blancos know that a deal will be difficult, they are hopeful that City's interest in Brighton & Hove Albion striker Evan Ferguson could make a deal possible.The Premier League champions are said to be willing to make an offer with £110 million to sign the 18-year-old Republic of Ireland international, who scored a hat trick in the 3-1 win over Newcastle United on Sept. 2.Real Madrid are most optimistic of being able to sign Alvarez, who they expect will become third choice at the Etihad if manager Pep Guardiola acquires Ferguson from the Seagulls. Such a move could trigger a domino effect, with the LaLiga side then looking to explore a €60m move for the former River Plate star.
