Christian Pulisic’s performances have reportedly caught the eye of a European giant.

According to Mundo Deportivo, Barcelona is closely monitoring the 18-year-old U.S. Men’s National Team winger. According to the report, Barca president Josep Maria Bartomeu is determined to not let the club fall into complacency and is hoping to add several younger options to compete with the team’s stars. Bartomeu reportedly wants to build a stronger core around Lionel Messi, Luis Suarez and Neymar as the club looks to prepare for the next decade.

Pulisic is reportedly one of many targets of those plans, although the report says that some within the club believe that the fee needed to sign the winger would be “absurd”. However, the club reportedly sees Pulisic as a player that can follow summer signings Samuel Umtiti and Lucas Digne in pushing some of the club’s regulars for time in the lineup. Among those stars is Messi, who the club is reportedly looking to push rather than ease into his decline.

After starting in Champions League action midweek, Pulisic and Borussia Dortmund return to action on Saturday against Ingolstadt.
