GUADALAJARA, Mexico – Edgar Castillo apparently has caught the eye of Brazilian teams during Club Tijuana's quarterfinal run in the Copa Libertadores.

According to a report at MedioTiempo.com, Tijuana sporting director Ignacio Palou has revealed that clubs in Brazil's top flight have made inquiries regarding the 26-year-old left back as the US international was a key player during Xolos' exciting showing during South America's premier club competition.

“Castillo caught their attention in Brazil,” Palou told MedioTiempo.com on Monday. “The truth is that we played three important Brazilian teams, with history and lineage and I think that we left a good taste, but they are only enquiries so far.”

Castillo missed the two Libertadores games against Corinthians, but was impressive against Palmeiras in the Round of 16 and against Atlético Mineiro in the quarterfinals, where Tijuana's run came to a disappointing end.

The New Mexico native is currently with the US national team, which heads to Jamaica on Tuesday ahead of Friday's World Cup qualifier in Kingston (9:30 pm ET, beIN Sport, live chat on MLSsoccer.com).

Palou was speaking ahead of the Liga MX draft, which takes place in Cancún on Wednesday.
