WEEKEND WATCH GUIDE

NWSL: Chicago at Portland, 3 p.m. Saturday, Lifetime. Early results are mixed, but both of these squads are expected to contend for an NWSL playoff spot this year. Keep an eye on Chicago's Julie Ertz, who has starred at center back for Chicago and the United States over the past few years. Ertz was moved up into an attacking midfield role last week and dominated. Will she do it again?

Liga MX: Tijuana at Tigres, 7 p.m. Saturday, Galavision. Tijuana is back in the league lead, with two games to play in the Clausura. Tigres — the Apertura champions — is currently on the outside of the playoff picture. In a reversal of recent years, Tijuana has been fine on the road lately, with four victories in its last six games. Can it knock Tigres out of playoff contention?

Premier League: Chelsea at Everton, 8 a.m. Sunday, CNBC. Two losses in five games have brought Chelsea back within Tottenham's sights. This is the league leader's most difficult game for the rest of the year, as Everton has improved throughout the year. Any dropped points by Chelsea could bring it back within a single bad result of losing the league lead.

Premier League: Arsenal at Tottenham, 10:30 a.m. Sunday, NBCSN. Unlike Spurs, Arsenal isn't chasing a league title, unless you count a spot in the Champions League, which manager Arsène Wenger once likened to a trophy in its own right. In sixth place with six games to go, Wenger's men need to win — and to get help from elsewhere — to land in the top four again.
