I think it means: [The team] has scored three goals. "team" is n-class in Swahili (timu), so it would use "imefunga" for its conjugation.
As a computer gamer, I immediately thought of a computer opponent. In that case, I think it works ^^ Also thought of Japanese robot football, which is of course not a sport to be underestimated.
That's really strange sentence. I am NOT funn of mpira wa miguu but....It has been scored three goals ? ( Yamefungwa magoli matatu ). They have scored three goals ? ( Wamefunga magoli matatu )
They have scored three goals (referring to team, which is obligate singular in AMERICAN English), would be a perfectly normal sentence. I'll try putting it in my next go-round and reporting it when it is marked wrong. I like the answer above from the computer gamer, it makes this make more sense.
