حارس المرمى قدام الجون.

A natural Egyptian pronunciation is:

ḥāris il-márma addām il-gōn

A slightly more careful breakdown:

• حارس = ḥāris
• المرمى = il-márma
• قدام = addām or qoddām / odām depending on speaker
• الجون = il-gōn

A few pronunciation notes:

• ح is a strong, breathy h sound, deeper than English h.
• ج in Egyptian Arabic is usually pronounced like English g in go, so جون sounds like gōn.
• The الـ article is usually pronounced il- in Egyptian Arabic.
• In fast speech, قدام is very often heard as oddam / addām.

Word by word:

• حارس = guard / keeper
• المرمى = the goal or the goal area/net
• قدام = in front of
• الجون = the goal

So حارس المرمى literally means keeper of the goal, i.e. goalkeeper.

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

So:

• حارس المرمى قدام الجون
  = The goalkeeper is in front of the goal

There is no separate present-tense is.

This is very normal in Arabic. Compare:

• أنا تعبان = I am tired
• البيت كبير = The house is big
• حارس المرمى قدام الجون = The goalkeeper is in front of the goal

If you wanted past or future, then Arabic would use other forms, but in the present, it is usually omitted.

This is a very common Arabic structure called an iḍāfa (possessive construction).

It works like:

• حارس = keeper / guard
• المرمى = the goal

Together:

• حارس المرمى = keeper of the goal = goalkeeper

This is how Arabic often says noun combinations that English puts into one word or uses as an adjective + noun combination.

Other similar examples:

• باب البيت = the door of the house = the house door
• مدرس اللغة العربية = the teacher of the Arabic language = the Arabic teacher

Because in an iḍāfa structure, definiteness is usually carried by the second noun.

So:

• حارس مرمى = a goalkeeper / goalkeeper
• حارس المرمى = the goalkeeper

Even though حارس itself does not have الـ, the whole phrase becomes definite because المرمى is definite.

This is a very important Arabic pattern.

قدام means in front of.

In Egyptian Arabic, it is a very common everyday word for position and location.

Examples:

• العربية قدام البيت = The car is in front of the house
• هو واقف قدام الباب = He is standing in front of the door

Depending on context, قدام can also sometimes mean before in a time-related sense, but here it clearly means in front of.

Yes, both relate to goal, but they are not exactly the same in feel.

• مرمى is an Arabic word meaning goal / target / goalmouth
• جون is a common football loanword from English goal

So:

• حارس المرمى is a standard Arabic way to say goalkeeper
• قدام الجون sounds very natural in spoken Egyptian football-related language

This kind of mixing is common in Egyptian Arabic, especially in sports vocabulary.

You may also hear:

• حارس الجون = goalkeeper
• قدام المرمى = in front of the goal

All of these are understandable, but the exact choice can depend on style, region, and how colloquial the speaker is being.

It is definitely Egyptian-flavored.

Reasons:

• قدام is very common in spoken Egyptian Arabic.
• الجون is a colloquial sports word.
• The pronunciation implied here is dialectal, not formal.

In Modern Standard Arabic, a more formal version might be something like:

• حارس المرمى أمام المرمى

But that sounds more formal and less like everyday Egyptian speech.

So the given sentence is best understood as spoken Egyptian Arabic.

Yes, it is normal.

The structure is:

• حارس المرمى = the subject
• قدام الجون = the location phrase

So literally:

• The goalkeeper — in front of the goal

This kind of subject + location structure is very common in Arabic, especially when the present-tense is is omitted.

In Egyptian Arabic, the definite article الـ is usually pronounced il- in normal speech.

So:

• المرمى → il-márma
• الجون → il-gōn

In Modern Standard Arabic, learners are often taught al-, but in Egyptian dialect il- is the normal everyday pronunciation.

Yes, a few:

• ح in حارس
  This is not the ordinary English h. It is stronger and more breathy.

• ر in حارس and المرمى
  It is usually a tapped or rolled r, not an English r.

• ج in الجون
  In Egyptian Arabic, this is usually g, not the j sound many learners expect from Standard Arabic classes.

• قدام
  The first consonant can vary in actual speech. Many Egyptians soften or reduce it, so learners may hear oddam rather than a clear dictionary-like qadām.

Yes, absolutely.

• قدام الجون = in front of the goal
• قدام المرمى = in front of the goal

Both make sense.

The difference is mostly in style and word choice:

• الجون sounds very colloquial and football-related
• المرمى is more Arabic and slightly less slangy

In real speech, Egyptians often use both kinds of vocabulary interchangeably, especially in sports contexts.
