Weekend watch guide

Premier League: Arsenal at Manchester United, 6:30 a.m. Saturday, NBCSN. If you watched the Premier League before 2004, you'll understand the excitement when teams once known as the Big Two play. Now this fixture has Man United manager Jose Mourinho, who fantasized in a book about punching Arsenal manager Arsene Wenger. It's like old times.

Bundesliga: Bayern Munich at Borussia Dortmund, 11:30 a.m. Saturday, Ch. 9. Every year, we wonder if a German team will challenge Bayern for first. Dortmund is six points back already this year, but the boys of BVB usually come the closest to Bayern — and no one believes in the other Bundesliga contenders. This is Germany's biggest game of the year.

La Liga: Real Madrid at Atletico Madrid, 1:45 p.m. Saturday, beIN. It's probably too early to call this a must-win for Atletico. Still, the Rojiblancos have fallen six points behind their crosstown rivals, who have yet to lose this season. If Atletico is going to challenge Real and Barcelona for the title, it starts here.

Serie A: Internazionale at AC Milan, 1:45 p.m. Sunday, beIN. Inter's plunge down the Serie A table makes this edition of the Milan derby slightly less meaningful than usual. I'm guessing, though, that none of the fans in the San Siro will particularly care. It should be an electric atmosphere when the two old rivals meet up again.
