Cầu thủ đá rất tốt.

A natural word-by-word breakdown is:

• cầu thủ = player / athlete, often a sports player
• đá = to kick; in sports contexts, often to play football/soccer
• rất = very
• tốt = good / well

So the structure is basically:

• Cầu thủ = the player
• đá rất tốt = plays very well / kicks very well

In Vietnamese, words like tốt often come after the verb to describe how an action is done.

So:

• đá tốt = kick/play well
• hát hay = sing well
• nấu ngon = cook well

This is different from English, where we usually use an adverb before or after the verb, as in plays well. In Vietnamese, an adjective-like word often fills that role after the verb.

It can mean both, depending on context.

In everyday Vietnamese, đá often means to play football/soccer, especially when the subject is a player:

• Cầu thủ đá rất tốt = The player plays very well

But literally, đá also means to kick. So without more context, the sentence could also be understood as The player kicks very well.

If you want to be more explicit, you can say:

• Cầu thủ đá bóng rất tốt = The player plays soccer very well

Vietnamese often leaves out words that are obvious from context.

So:

• đá bóng rất tốt = plays soccer very well
• đá rất tốt = plays very well / kicks very well

If everyone already knows you are talking about soccer or football, bóng can be omitted. This is very normal.

Cầu thủ is a noun meaning player in a sports sense, especially an athlete on a team. In everyday usage, many people strongly associate it with football/soccer players, though it can be broader depending on context.

It is not the same as English player in every sense. For example, it would not normally mean a piano player or a game player.

The basic pattern is:

• Subject + Verb + Degree word + descriptive word

In this sentence:

• Cầu thủ = subject
• đá = verb
• rất = degree word
• tốt = descriptive word meaning well/good

So the sentence follows a very common Vietnamese pattern:

• Ai / cái gì + làm gì + như thế nào
• Who/what + does what + how

Yes, tốt is basically an adjective meaning good, but Vietnamese often uses adjectives in places where English would use adverbs.

So:

• tốt literally = good
• đá tốt = kick/play good → natural English: kick/play well

This is a very common difference between Vietnamese and English.

Rất means very and intensifies tốt.

So:

• đá tốt = plays well
• đá rất tốt = plays very well

It normally comes before the adjective or descriptive word it modifies:

• rất tốt = very good
• rất hay = very good / very skillful / very interesting, depending on context

Yes, absolutely.

• Cầu thủ đá tốt = The player plays well
• Cầu thủ đá rất tốt = The player plays very well

Removing rất just makes the statement less strong.

Vietnamese verbs do not change form for tense the way English verbs do. So đá does not itself mean specifically plays, played, or will play.

Cầu thủ đá rất tốt is often understood as a general present statement:

• The player plays very well

But depending on context, it could also refer to the past or another time. If you want to mark time clearly, Vietnamese usually adds time words, for example:

• Hôm qua cầu thủ đá rất tốt = Yesterday the player played very well
• Hôm nay cầu thủ đá rất tốt = Today the player is playing very well

A rough guide:

• cầu thủ

  • cầu has a falling-rising type contour with the dấu huyền on â? Actually here the tone is on ầ, a low falling tone in the northern standard.
  • thủ has the hỏi tone, a dipping tone in the north

• đá

  • has the sắc tone, a rising tone

• rất

  • has the sắc tone on ấ, and the final t stops the syllable sharply

• tốt

  • has the sắc tone on ố, also ending with a sharp final t

A rough northern-style approximation is something like:

• cầu thủ đá rất tốt
• kəu thu? da raht toht

But it is much better to learn from audio, because Vietnamese tones and vowel quality matter a lot.

Yes, but the nuance changes a little.

• đá rất tốt = plays very well
• đá rất giỏi = is very skilled at playing

Both are natural. In many contexts they are close in meaning, but:

• tốt often describes the quality of the performance
• giỏi emphasizes skill or ability

So giỏi can sound a bit more like talented/skilled, while tốt is often a straightforward well.

Vietnamese often does not mark the and a/an the way English does.

So cầu thủ can mean:

• the player
• a player
• players in some contexts, though this sentence most naturally sounds singular

You choose the best English translation from context. If the player has already been mentioned, the player is often the most natural translation.

Yes, it is natural and understandable. It sounds like a short comment or evaluation, especially in a sports context.

For example, someone watching a match might say:

• Cầu thủ đá rất tốt. = The player is playing very well.

If the context is specifically soccer, many speakers might also say:

• Cầu thủ này đá rất tốt. = This player plays very well.
• Cầu thủ đó đá rất tốt. = That player plays very well.
• Cầu thủ này đá bóng rất tốt. = This player plays soccer very well.

Those versions can sound a little more specific.
