Gregor Townsend believes his side will need to have their wits about them if they are to beat Zebre in the final match of the RaboDirectPRO12 season. Glasgow Warriors have already qualified for the play-offs, but a win against the Italians could see them climb to number one seed and with it book a home semi-final. Warriors have won their last seven RaboDirect PRO12 matches which equals their best ever run, set last season. Moreover, they have not lost to an Italian opponent since Treviso visited Firhill in September 2011. But Townsend is wary of the threat that Zebre will carry and is hoping that his side can maintain their high standards. "We face a very tough game tomorrow night against an in-form Zebre side who have beaten the likes of Ospreys and Edinburgh in recent weeks,” said Townsend. "Zebre are engaged in a battle with Treviso to represent Italy in the inaugural European Rugby Champions Cup next season and having just climbed above their rivals in the league, they will be determined to stay there by beating us at Scotstoun. "I was absolutely delighted with the quality of our performance at Treviso last weekend but in order to secure home advantage in the play-offs, for the very first time, we will have to make sure that we maintain our standards tomorrow night. "In our last two home matches against Ulster and Edinburgh we have had record crowds, which shows how much our support has grown in recent years. "We're hoping for another big crowd tomorrow night for what is a massive game for the club." Last week’s hat-trick hero Tommy Seymour will be replaced by the returning Sean Lamont for Glasgow. Alex Dunbar starts at outside centre and Duncan Weir, Ryan Grant Moray Low and skipper Al Kellock all return. Meanwhile, Tommaso Iannone comes in for Luciano Orquera and Gugielmo Palazzani and Giulio Toniolatti both start for the Italians. Zebre currently hold the Italian qualification spot for the European Champions Cup next year and simply need to gain as many league points as Benetton Treviso do from their round 22 fixture to secure that spot, providing they maintain their match points difference. Zebre have won their last two matches against Edinburgh and Ospreys, which is already a club record. Glasgow have taken all their previous clashes with Zebre although the Italians did gain a losing bonus point in their fixture in Parma in round four. At Scotstoun, 6.30pm.
