Steve Harper felt Newcastle's second leg Uefa Cup tie with Zulte-Waregem had been a 'no-win' situation.
The Magpies effectively secured their passage to the last 16 with a convincing 3-1 victory in Belgium last week, and never got out of second gear as they won the return leg 1-0.
But Harper was just pleased to see his side get the job done and progress to a meeting with AZ Alkmaar in the last 16.
"We did the job away from home and tonight was a no-win situation - but a great finish from Obafemi (Martins) won it for us," the goalkeeper told Five.
"When a team come and set themselves up like that it's a big compliment.
"They had 11 men behind the ball and made it hard - we couldn't find a way through in the first half.
Harper is now expecting a difficult clash against Dutch side AZ, who scraped past Fenerbahce on away goals.
"It will be very tough," he predicted.
"They have performed well in the last couple of years - but we are confident we can progress."
