Đội kia thua rồi.

In Vietnamese, demonstratives like this and that usually come after the noun, not before it.

So:

• đội kia = that team
• đội này = this team
• đội đó = that team

This is a very common Vietnamese pattern: noun + demonstrative.

Kia usually means that ... over there or that other ..., often with a sense of distance or contrast.

So đội kia can mean:

• that team over there
• that other team

In a sports context, it can sound very natural as the other team.

Both kia and đó can often be translated as that, but they are not always identical.

A simple way to think about it:

• đó = more neutral that
• kia = that one over there / that other one, often more contrastive or more distant

So:

• đội đó = that team
• đội kia = that team over there / the other team

In real speech, the difference is sometimes subtle and context matters.

Thua is a verb. Here it means to lose or to be defeated.

So the sentence structure is basically:

• Đội kia = subject
• thua rồi = predicate

Vietnamese does not need a word like to be here. You do not say something equivalent to is lose. The verb thua works directly.

Because Vietnamese often leaves out information that is already clear from context.

Thua can take an object, for example:

• Đội kia thua đội này. = That team lost to this team.

But if everyone already knows who they lost to, you can just say:

• Đội kia thua rồi.

That simply means That team lost or That team has already lost.

Rồi adds the idea that something has already happened or is now completed.

So thua rồi suggests:

• the losing has already happened
• the result is now clear
• the situation has changed and is settled

That is why the sentence can feel like:

• That team has lost.
• That team already lost.
• That team is done for.
  (depending on context)

It can match either one, depending on context.

A good practical rule is:

• thua = lose / lost
• thua rồi = has lost / already lost / lost now

Because of rồi, the sentence often feels a bit closer to has lost or already lost than to a simple past statement with no extra nuance.

Yes, you can. But the feeling changes.

• Đội kia thua. = That team loses / lost / is losing, depending on context
• Đội kia thua rồi. = That team has already lost / has now lost

Adding rồi makes the result sound more final and established.

Yes, both are possible.

Roughly:

• Đội kia thua rồi. = That team has lost / already lost.
• Đội kia đã thua. = That team lost / had lost.
• Đội kia đã thua rồi. = That team had already lost / has definitely already lost.

A simple distinction:

• đã often marks past time
• rồi often marks completion or a resulting state

In everyday speech, thua rồi is very natural when the context already makes the timing clear.

The basic word order here is the normal one:

• Đội kia = noun phrase
• thua rồi = verb phrase

So Đội kia thua rồi is the natural order.

You would not normally say something like Kia đội thua rồi. Vietnamese is not like English only in word order details, but this particular noun phrase pattern is quite fixed: noun + demonstrative.

The tones are:

• đội: nặng tone
• kia: ngang tone
• thua: ngang tone
• rồi: huyền tone

So the sentence has this tone pattern:

• đội — heavy, short, low/glottalized
• kia — level
• thua — level
• rồi — falling

For many learners, the most important parts to notice are đội and rồi, because their tones are more marked.
