In the field of...,

[Silverobama]

Please help me with the following short paragraph.

In the field of soccer there's a pretty weird phenomenon. The supporters of Leo Messi always don't see eye to eye with stalwarts of Cristiano Ronaldo. The cause of the phenomenon might arise from who the best modern-day soccer player is. Supporters on both sides more often than not insult and abuse each other when one of the stars perform well in a match while Messi and Ronaldo are seemingly to be friends of each other.

In the field of soccer, there's a pretty weird phenomenon.

Note the extra punctuation.

The Supporters of Leo Messi always don't see eye to eye with stalwarts those of Cristiano Ronaldo.

1. It's more natural to say "[Leo] Messi fans" and "[Cristiano] Ronaldo fans". People support a club but they're usually fans of a specific player.
2. Also, by "always don't see eye to eye" do you mean a) they always disagree or b) they don't always agree?

The cause of the phenomenon might arise from who the best modern-day soccer player is.

That's not an explanation of the cause of the rivalry between the two sets of fans.

Supporters on both sides more often than not insult and abuse each other when one of the stars perform well in a match, while Messi and Ronaldo are seemingly to be friends of with each other.

See above. Note that you don't really need the last three words.

2. Also, by "always don't see eye to eye" do you mean a) they always disagree or b) they don't always agree?

I want to say that they always disagree with each other.

That's not an explanation of the cause of the rivalry between the two sets of fans.

Why? Could you please explain in more depth? Leo fans always think Leo is the best player and then verbally attack Ronaldo fans. Ronaldo fans also do the same things because they believe Ronaldo is the best player and this has made the phenomon that fans of each side would inevitably abuse each other online.

Note that you don't really need the last three words.

Is the whole paragrpah good now?

Then that's what you should say. Your original was at best unnatural and at worst ungrammatical.

Why? Could you please explain in more depth? Leo fans always think Leo is the best player and then verbally attack Ronaldo fans. Ronaldo fans also do the same things because they believe Ronaldo is the best player and this has made the phenomon that fans of each side would inevitably abuse each other online.

Because you didn't make it clear that the cause is simply their opinion about who is the best player. You said the problem was caused by "who the best player in the world is".

Is the whole paragraph good OK now?

See above.

In the field of soccer, there's a pretty weird phenomenon. Leo Messi fans always don't see eye to eye disagree with those of Cristiano Ronaldo. The cause of the phenomenon might arise from be their differing opinions on who the best modern-day soccer player is. Supporters on both sides more often than not insult and abuse each other when one either of the stars players performs well in a match, while Messi and Ronaldo are seemingly friends.

I'd open with just "In soccer" but yours isn't grammatically incorrect.
