Por mais que o goleiro defenda, o atacante continua chutando.

In this sentence, por mais que means something like no matter how much, however much, or even if.

So:

• Por mais que o goleiro defenda...
  = No matter how much the goalkeeper saves/blocks...
• ...o atacante continua chutando.
  = ...the attacker keeps shooting.

It introduces a contrast: one thing keeps happening despite another thing.

A very similar English idea is:

• No matter how much the goalkeeper saves, the attacker keeps shooting.

Because por mais que usually triggers the subjunctive.

The verb defender in the present subjunctive for ele/o goleiro is:

• que eu defenda
• que você/ele/ela defenda

So:

• Por mais que o goleiro defenda...

This is not talking about one simple factual action in a straightforward way. It expresses concession: even if / no matter how much.

Compare:

• O goleiro defende bem. = The goalkeeper defends well.
  → normal statement, so indicative
• Por mais que o goleiro defenda... = No matter how much the goalkeeper defends/saves...
  → concessive idea, so subjunctive

Yes. In soccer Portuguese, defender can mean to save, to block, or to stop a shot.

So o goleiro defende can mean:

• the goalkeeper makes saves
• the goalkeeper blocks shots

Depending on context, English may translate it more naturally as save rather than defend.

Chutando is the gerund of chutar, meaning kicking or, in soccer, shooting.

In sports context:

• chutar = to kick / to shoot
• continua chutando = keeps kicking / keeps shooting

Because this is about o atacante and o goleiro, the most natural English meaning is probably keeps shooting.

Portuguese often uses continuar + gerund in Brazilian Portuguese to mean keep doing something or continue doing something.

So:

• continua chutando = keeps shooting / continues shooting

In Brazilian Portuguese, this is very common and natural.

You may also hear:

• continua a chutar

That is grammatical, but in Brazil continuar + gerund is usually more common in everyday speech.

Portuguese uses definite articles more often than English.

Here:

• o goleiro = the goalkeeper
• o atacante = the attacker/striker

Even when English might sometimes omit an article in a more general statement, Portuguese often keeps it.

This sentence sounds like it is talking about the goalkeeper and the attacker in a specific game situation, or about those roles in a general but still definite way.

The comma separates the concessive clause from the main clause:

• Por mais que o goleiro defenda,
• o atacante continua chutando.

This is similar to English punctuation in a sentence like:

• No matter how much the goalkeeper saves, the attacker keeps shooting.

The first part sets up the contrast, and the second part gives the main result or continuing action.

Sometimes yes, but the meaning changes slightly.

• Por mais que = no matter how much / however much
• Mesmo que = even if
• Embora = although / even though

Examples:

• Por mais que o goleiro defenda, o atacante continua chutando.
  = No matter how much the goalkeeper saves, the attacker keeps shooting.

• Mesmo que o goleiro defenda, o atacante continua chutando.
  = Even if the goalkeeper saves, the attacker keeps shooting.

• Embora o goleiro defenda, o atacante continua chutando.
  = Although the goalkeeper saves, the attacker keeps shooting.

So por mais que especially emphasizes quantity/intensity/repetition.

In this kind of concessive structure, yes, it normally takes the subjunctive.

Examples:

• Por mais que eu estude, ainda erro.
• Por mais que ela tente, não consegue.
• Por mais que o goleiro defenda, o atacante continua chutando.

So if you learn por mais que + subjunctive, that will serve you well.

Because the sentence expresses a general situation, a repeated pattern, or something happening right now in a vivid way.

• o goleiro defenda → present subjunctive
• o atacante continua chutando → present indicative + gerund

This can mean:

• a general truth in that scenario
• a recurring action in a match
• a live-description kind of feeling

Portuguese often uses the present this way, just like English can:

• No matter how much the goalkeeper saves, the attacker keeps shooting.

In soccer, atacante often refers to an attacking player, and depending on context it may be translated as:

• attacker
• forward
• striker

So in natural English soccer language, the striker keeps shooting may sound more idiomatic than the attacker keeps shooting.

Yes. Chutar has a few meanings in Portuguese.

Common ones include:

• to kick
• to shoot (in soccer)
• to guess (informally)

Examples:

• Ele chutou a bola. = He kicked the ball.
• Ele chutou para o gol. = He shot at goal.
• Vou chutar: uns 20 minutos. = I’m going to guess: about 20 minutes.

In your sentence, because of goleiro and atacante, it clearly means shooting/kicking at goal.

A few natural translations would be:

• No matter how many saves the goalkeeper makes, the striker keeps shooting.
• No matter how much the goalkeeper blocks, the attacker keeps shooting.
• However many times the goalkeeper saves it, the striker keeps taking shots.

This is useful because the Portuguese sentence is very natural, but a word-for-word translation like the attacker continues kicking may sound less natural in sports English than keeps shooting or keeps taking shots.
