Outlook: In the first of three friendlies planned this year, United will face a Spanish club that finished La Liga’s campaign Sunday with a surprise victory at Real Madrid and finished 10th among 20 teams with a 14-16-8 record.
For the other friendlies, Olympique Marseille will visit Audi Field in July and a Latin American foe, probably from Mexico, will come in September.
Sevilla-based Betis — which will play at lower-tier Chattanooga FC on Saturday — was the first club since 2002-03 to win at Barcelona (4-3) and at Real Madrid (2-0) in the same season.
