World cup main man mane critical to senegal hopes in colombia showdown

I think there may be a few errors in your sentence!

Here's a corrected version:

"World Cup main man Sadio Mané critical to Senegal's hopes in Colombia showdown"

Here's a breakdown of the corrections:

• "main man" is a colloquialism that means "star player" or "key player", so I kept it as is.
• "Mane" is the correct spelling of the player's name, not "Mane".
• "Senegal's hopes" is the correct phrase, as Senegal is the country and "hopes" is the correct verb form.
• "Colombia showdown" is a bit informal, but I kept it as is, as it's a common way to refer to a high-stakes match.

So, the corrected sentence is: World Cup main man Sadio Mané critical to Senegal's hopes in Colombia showdown.
