Florentin Pogba has said he will foul brother Paul Pogba if that is what it takes to help St Etienne beat Manchester United in their Europa League tie.
Florentin, 26, will meet Paul, 23, when the Ligue 1 travel to Old Trafford on Thursday for the first leg of their round-of-32 match.
"We're both determined players," Florentin, whose twin brother Mathias plays for Sparta Rotterdam, told Telefoot. "Him and me. If he's on a run, and I have to tackle him, I'll tackle him. I'm not going to knock him out. But if I have to foul him, I'll do it.
