Wellington Phoenix coach Ricki Herbert insists the club is feeling no extra pressure ahead of Sunday's clash with Melbourne Heart.

The New Zealand club have equalled the record for most matches (23) undefeated at one venue (Westpac Stadium) and need to record just a draw against the Heart to break Sydney United's old National Soccer League record.

But Herbert admits the record would be nice although is not something the players are concerned about heading into the Week 10 clash.

"It's an incredible statistic and I'm not sure any other team in this league will ever beat it but I don't think there's any extra pressure on at all," he said.

"It's been sitting there for us for a while now and there has been a lot of attention around how long we can keep the run going.

"Hopefully we can do it."
