Munster motivation not a problem for returning Ulster skipper Muller
Muller, who will feature in a much-changed starting line-up to that which went down 42-13 to Leinster on Monday, knows also that it is a must-win game for his side if they still harbour ambitions of reaching the knock-out stages.
Ulster are currently lying in ninth spot and a victory will also give them confidence in the run-up to the third round of games in Europe.
