Ezequiel Barco returned to training with Atlanta United on Tuesday, just as manager Gerardo Martino said he would last week. A team spokesman confirmed Barco’s return.

Barco, who at a reported $15 million is the most expensive transfer in MLS history, has yet to debut with the Five Stripes after he sustained a quad injury during preparation for season-opening game at Houston.

The 19-year-old midfielder is a native of Argentina. Atlanta United acquired him from Independiente. The team (4-1-0) has won four consecutive games and will host NYCFC on Sunday at Mercedes-Benz Stadium.
