Liverpool has signed Colombia U20 international Anderson Arroyo and sent the youngster straight out on loan to Real Mallorca. The 18-year-old defender joins the Anfield club from Fortaleza CEIF in Colombia but will go straight to the Spanish third tier on a 18-month deal. Despite his age, highly-rated Arroyo has appeared 22 times for his former club's first team over the past three seasons after making his debut at just 15. Arroyo is considered a potential long-term solution to Liverpool's defensive woes and joins Segunda B leaders Mallorca, who were relegated last season, for the rest of the season.
