Mahrez is "Plan A", but if Roma can not close for the Algerian then their "Plan B" is Real Madrid's Lucas Vazquez. The Spaniard, born in 1991, grew up in Real Madrid's youth team and last season, he made 50 appearances with 4 goals and 14 assists.
Roma are still insisting for Mahrez, as they are hoping to find a deal with Leicester (they are asking for 40 million euros). The Giallorossi still have not found a deal yet and are evaluating other options. The alternative to Mahrez is Lucas Vazquez.
