Suarez last Sunday was caught up in another row following his handball in the build-up to his goal in the 2-1 FA Cup win over non-league Mansfield.
United full-back Buttner has laid into Suarez on Twitter ahead of tomorrow’s clash, reports The Sun.
Buttner said: “Mansfield deserved a draw at the very least. What a handball by Luis Suarez!
“It’s FOOTBALL, mate, not HANDBALL.”
