Aston Villa has identified 21-year-old French goalkeeper Robin Risser of RC Lens as a primary target, as the club prepares for the potential departure of Emiliano Martinez. The transfer is considered complex because RC Lens is not planning to sell the player and would require a very high offer. Risser, who has five caps for France U21, has also been linked with other clubs including Newcastle United and Tottenham Hotspur.
