True. However, pride took a role in that statement like PS said imo. Speed is his thing, so the moment he faces someone comparable or even slightly superior to him in speed, his pride comes out
On panel, FF was keeping up with them just fine. With his flashy fist, he even landed several hits on PS, who just ultimately countered with a defensive technique, and superior physical power
And the moment, PS overpowered him, Garou directly went for him, the moment he was ready to counter Garou, PS jumped on him, which was his intention since the beginning(finishing FF first to have his one on one with Garou), which is something that can't happen in a 1 on 1
