LISBON, Portugal — Freddy Adu came on to score the tying goal in Benfica’s 1-1 draw with Setubal in their fourth-round Portuguese league cup match Saturday.

The 18-year-old U.S. international angled his shot home in injury time to equalize after appearing as a substitute in the 71st minute. Matheus earlier gave the visitors a 12th-minute lead.

Adu also scored a late equalizer in the previous round against Amadora in September. Benfica went on to win that game on penalties.

One of the highest-profile players in U.S. soccer, Adu has seen little action since joining the Lisbon club from Real Salt Lake in July for a $2 million transfer fee. He made his league debut as a substitute last month and played in one Champions League game in August, again as a substitute.

Adu has two national team appearances for the U.S. He became the youngest player in the history of the U.S. team when he joined it as a 16-year-old.
