الفريق هيدافع حتى لو المهاجم تعبان.

A natural Egyptian-style pronunciation is:

il-farīʔ haydāfeʕ ḥatta law il-mohāgem taʕbān

A rough word-by-word guide:

• الفريق → il-farīʔ = the team
• هيدافع → haydāfeʕ = will defend
• حتى لو → ḥatta law = even if
• المهاجم → il-mohāgem = the attacker / striker
• تعبان → taʕbān = tired

It marks the future in Egyptian Arabic.

• يدافع = he defends / he is defending
• هيدافع = he will defend

In Egyptian, the future is often made by adding هـ or حـ to the present-tense verb. So this is the equivalent of will defend or sometimes is going to defend.

Because in Arabic, the verb to be is usually not stated in the present tense.

So:

• المهاجم تعبان literally looks like the attacker tired
• but it means the attacker is tired

This is very normal in both Egyptian Arabic and Standard Arabic.

Because تعبان here is the predicate of the sentence, not an adjective directly attached to the noun.

• المهاجم تعبان = the attacker is tired
• المهاجم التعبان = the tired attacker

So if you add ال to تعبان, you change the structure from a full sentence into a noun phrase.

حتى لو means even if.

• لو by itself = if
• حتى لو = even if

So this phrase adds a stronger concessive idea:

• الفريق هيدافع حتى لو المهاجم تعبان = the team will defend even if the attacker is tired

Because subject-first order is very common in Egyptian Arabic.

So:

• الفريق هيدافع = the team will defend

This is a very natural spoken Egyptian pattern. Arabic can also use verb-first order in some contexts, but subject + verb is especially common in everyday Egyptian speech.

In a sports context, المهاجم usually means:

• attacker
• striker
• forward

So in this sentence, it most likely refers to an attacking player on a team.

Outside sports, it can also mean attacker/assailant, but here the sports meaning is the natural one.

Yes, but the meaning changes.

• الفريق هيدافع = the team will defend / is going to defend
• الفريق بيدافع = the team defends / is defending / tends to defend

In Egyptian Arabic, بـ often marks the present or habitual sense, while هـ/حـ marks the future.

Because it agrees with المهاجم, which is masculine singular.

If you changed the noun, the adjective would change too:

• masculine singular: المهاجم تعبان
• feminine singular: المهاجمة تعبانة
• plural: المهاجمين تعبانين

So the form of tired changes to match the person or people being described.

It is very understandable as Egyptian Arabic, but some words are also shared with Standard Arabic.

What feels especially Egyptian here is:

• هيدافع for the future

Words like these are common in both:

• الفريق
• المهاجم

A more Standard Arabic version might be something like:

سيدافع الفريق حتى لو كان المهاجم متعبًا

So the sentence you were given is a natural everyday Egyptian-style sentence, especially because of هيدافع.

It breaks down like this:

• الفريق = the team
• هيدافع = will defend
• حتى لو = even if
• المهاجم = the attacker
• تعبان = tired

So the pattern is:

subject + future verb + even if + subject + adjective

That last part, المهاجم تعبان, is a small sentence inside the bigger sentence. It literally means the attacker is tired.
