HARRISON, N.J. — It took three games, but New York City FC was welcomed to Concacaf in the worst way possible on Wednesday night.

It lost a Concacaf Champions League home game — two minutes into stoppage time.

Eduardo Vargas scored off a rebound to lift Tigres UANL to a 1-0 victory in the first leg of the quarterfinals before 10,212 at Red Bull Arena.

The stunning defeat left NYCFC a goal down — an away goal, which will count as double, prior to next Tuesday’s second leg at Estadio Universitario in Monterrey.

NYCFC had no one else but itself to blame as it squandered several first-half chances to take the lead.

City will host FC Dallas in its home opener at Yankee Stadium on Saturday at 12:30 p.m.
