Ulster hooker Best expects tough test in Montpellier

International hooker Rory Best knows Ulster will come under fierce pressure in Saturday's Heineken Cup match away to Montpellier.

Ulster won their first Pool Five game at home to Leicester last weekend while the French side saw off Treviso 27-10.

"The away games in this competition really test your mettle and Montpellier could put a big score on if we don not turn up," said Best.
