Bundesliga: Schalke at Bayern Munich, 11:30 a.m. Saturday, Ch. 9. With five games to go in the German season, Bayern — seven points up on Borussia Dortmund — is close enough to taste a fourth consecutive league title. Schalke, though, has plenty at stake, only four points out of third place. The visitors drew 2-2 with Dortmund last week; can they bring down another giant?

Premier League: West Ham at Leicester City, 7:30 a.m. Sunday, NBC Sports. Seven points up with five games to play. Leicester City is so close to perhaps the most improbable league title in soccer history. With West Ham playing well and chasing a potential Champions League spot, this may well be the most difficult test remaining for Leicester, but the Foxes have surmounted every hurdle so far.

MLS: Sporting Kansas City at Dallas, 6 p.m. Sunday, FS1. This will be an early test for two of the teams that appear to be among the class of the Western Conference. Both teams have endured early hiccups — a pair of home losses for KC, and for Dallas, a beating at the hands of cross-state rivals Houston — but have otherwise been excellent. The midfield play on both sides will be the key to the outcome.

NWSL: Orlando at Portland, 9 p.m. Sunday, nwslsoccer.com. The final game of the NWSL’s opening weekend is the marquee matchup, as Alex Morgan visits her former team with the rest of the Orlando expansion team. Portland may have the home advantage, but almost seems to have as many new faces as Orlando. Given that this is each team’s opening game, it may be a bit tentative.
