Northampton Saints full-back Ben Foden believes his side 'owe Munster' following their dramatic defeat at Thomond Park back in Round 1.
A last-minute drop goal from Ronan O'Gara snatched victory for Munster in November as the Saints looked on course for a famous opening win.
This weekend the two sides meet once again with stadium:mk hosting the clash and Foden is looking forward to the challenge.
"There's no bigger occasion than playing Munster in the Heineken Cup," he told BBC Radio Northampton.
"We owe them one.
"We're look forward to it - we want to keep the winning ways going."
The match kicks off at 18:00 on Saturday January 21.
