Soccer is by far Portugal's most popular sport, and Lisbon has three teams, which play at least weekly during the September–May season. Although you can buy tickets on the day of a game at the stadiums, it's best to get them in advance from the ABEP booth in the Praça dos Restauradores.
Arrive at matches early; there's usually a full program of entertainment first, including children's soccer, marching bands, and fireworks. Before every Benfica home game the club’s emblem, an eagle, swoops around the stadium. Be wary of pickpockets in soccer stadium crowds.
