• Premier League: Arsenal at Tottenham, 6:45 a.m. Saturday, NBC Sports. The contentious North London derby has rarely had such title implications. Arsenal renewed its reputation as a collection of choke artists with a pair of losses to lesser teams in the past week; Tottenham, in second place, can boost its own fortunes and effectively end its rival’s already-wobbly title chances.


• Bundesliga: Bayern Munich at Borussia Dortmund, 11:30 a.m. Saturday, FX. Dortmund has, somehow, pulled back within five points of Bayern’s lead in the Bundesliga. For most of the season, it appeared that Bayern would cruise to the title, but if BVB can get a home win in this game, it will make the final weeks of the German season very interesting.


• MLS: Columbus at Portland, 3:30 p.m. Sunday, ESPN. The first nationally televised game of the 2016 MLS season is a rematch of the 2015 title game. Portland begins its title defense with perhaps its most optimistic outlook in years, as its attacking core has stayed intact. Columbus just signed all-star striker Kei Kamara to a new contract, to go with last year’s 22 goals, and is out for revenge.


• MLS: Sporting KC at Seattle, 6 p.m. Sunday, FS1. Seattle begins its new life without talismanic striker Obafemi Martins, who received a gigantic payday in China. In his place, though, is national-team youngster Jordan Morris, the most heavily hyped MLS rookie in years. Kansas City is hoping to erase memories of last year’s second-half swoon; striker Dom Dwyer will need to carry the load up front.
