Learn Arabic (Modern Standard): فريقنا هو الفريق الذي فاز بالكأس.

The word الذي means 'that' or 'which' for masculine singular nouns. We use it here because it links back to الفريق (the team), which is a masculine noun in Arabic. If the noun were feminine, we would use التي.

Why is the word هو (he/it) in the middle of the sentence when the translation says 'is'?

Arabic doesn't have a direct verb for 'is' in the present tense. However, when a sentence links two specific, defined nouns like فريقنا (our team) and الفريق (the team), Arabic often inserts a pronoun like هو between them. This acts like a bridge to make it clear that the sentence means 'Our team IS the team.'

Why is there a بـ attached to the beginning of the word for cup (بالكأس)?

In Arabic, the verb فاز (won) is almost always paired with the attached preposition بـ (with / by) to show what prize or game was won. So, instead of saying 'won the cup' directly, Arabic literally says 'won with the cup' (فاز بالكأس).

How does the word فريقنا mean 'our team'?

The base word is فريق (team). To say 'our', we attach the possessive suffix ـنا to the end of the word. Because it has this possessive ending, the whole word فريقنا is treated as a specific, defined noun, just like a word starting with الـ (the).
