In the following conditional sentence, which modal verb [STRIKE]suits the[/STRIKE] works best? Are they both correct?

1. If nobody supports me, I cannot win the table tennis match.
2. If nobody supports me, I will not be able to win the table tennis match.

Please note my corrections above. While it's possible to use "can" followed by "not" (as a separate word), you needed the single word "cannot" here. There is no need to capitalise "tennis".

Sentence #2 is the more natural. Most native speakers would say "I won't be able to win" or just "I won't win". It would be used before the match starts.

If the match has already started, sentence #1 is possible, although "the" would probably change to "this". If you imagine that a player is disappointed that nobody in the audience seems to be supporting them, they might say, exasperatedly, "If nobody supports me, I can't win this match!"
