Wales skipper Ashley Williams has insisted that the togetherness in the camp will be enough to get his side back on track when they face Serbia in Belgrade.

The Dragons have ground to make up on their Group D rivals, finding themselves four points adrift of the joint-leaders midway through the World Cup qualifying campaign.

Williams, a part of the squad that fell to a 6-1 reverse up the road in Novi Sad five years ago, is adamant that Wales will thrive under pressure in front of a partisan crowd at the Rajko Mitic Stadium on Sunday evening.

"We're still in a good position halfway through," he told reporters. "I live for [games like these]. As a team, we live for these nights. It doesn't always come off. I think we've seen that before in the past.

"But of late, this is the kind of game we love, when you're up against it in a different country, you're working hard and you're backing your mates up. Once you get in that groove, it's difficult to beat.

"We're very resilient and we're a gritty team. This is another opportunity for us to go out there and show our togetherness, put in a big shift and hopefully get the result we want."

Wales have had a mixed campaign to date, winning their opening qualifier against Moldova but then drawing four in succession.
