How do I say "did you watch the football?" With the World Cup on, this is a common phrase I want to be able to ask. Is it simply 你看足球了吗？Or 足球比赛？And do I need the 了 in this sentence? Including the 了 makes it feel like I'm asking them "do you watch football these days, as opposed to before when you didn't?" Or should I put the 了 after the 看 instead of at the end of the sentence?
"你看足球比赛吗？" = "do you watch football match?"
"你看了足球比赛吗？" = "have you watched the football match? " (看 is the verb, 了 is the verb particle indicates 'completion of an action-- 足球比赛 is the object that was being watched)
"你看足球比赛了吗？" put the object '足球比赛' between '看' and its verb particle '了'. that make '看足球比赛' a verb phrase


If you want to ask if someone watched the football match, #2 and #3 are both acceptable.
