Which if the record you think that is unbreakable and state the reason.

1. 91 Goals in One calendar year by Messi

2. 3 World cup by Pele

3. 17 Goals in 1 champion league CR7

4. 5 Goals in 9 minutes by Robert Lewandowaki

My view

To break Messi 91 Goals in calendar year possible to me, it’s not really hard to break, expecially in Spanish league and Germany.

CR7 17 Goals in a season also wouldn’t be that hard to break. it’s likely Lewandowaki or halland break this year.

The most difficult would be Pele’s 3 times World cup record.

also, Lewandowaki is also tough but I give it to Pele record
