BARCELONA, Spain — Radamel Falcao struck a free kick in the 90th minute to give unbeaten Atletico Madrid a 1-0 victory at Real Sociedad on Sunday, extending its winning run to seven games to remain level with Barcelona at the top of the Spanish standings.

After being held in check until the very end, Falcao curled a perfect right-footed shot over the defensive wall to take his league scoring tally to nine goals, two behind leader Lionel Messi of Barcelona.

Atletico has won 11 of 12 games in all competitions as second-year coach Diego Simeone continues to forge Spain's best chance of a side capable of mounting a challenge to Barcelona and Real Madrid's recent domestic dominance.
