There is no bigger motivation for Leinster to win in Glasgow this weekend; maximum points will see the Irish Province return to the summit of the table and scrum-half Luke McGrath is determined to get one over on the Warriors. Leinster have lost just once in the Guinness PRO12 since round four: 23-13 to Newport Gwent Dragons at Rodney Parade in January, with the Leinstermen's only defeat to a Scottish opponent in their last five such encounters was against Edinburgh. Leinster won 23-18 at the RDS Arena in round five and have achieved a regular season's double over the Warriors only once since season 2005/06 and that was in 2012/13. Leinster's only previous victory at Scotstoun was 6-0 in November 2012 – that was also the only time that the Warriors have been nilled at home. Leinster Rugby head coach Leo Cullen has made eight changes in total from the XV that accounted for the Ospreys last time out. And there’s a welcome return from injury for Ireland international Dave Kearney, while Academy back Joey Carbery is in line to make his debut from the bench. "The last four games we've got 18 out of 20 points, so it's a good place to be at the moment," McGrath said of the recent run of positive results. "It's been good – I've been playing anyway, which is a good sign. There's always bits and pieces to improve each game and I've been working hard on that. “But four wins, you've got to be happy with that. Personally I've been happy but there's definitely things I can improve on." This round-nine game was postponed from its original date in early December due to weather conditions. Glasgow Warriors have lost just one of their last six first team fixtures: 13-10 away at Ulster in February, while the Warriors solitary defeat at Scotstoun since September was 26-15 to Northampton in the European Champions Cup on 21 November. Rory Clegg has been named in the Glasgow Warriors starting XV, while backrowers Adam Ashe and Tyrone Holmes both return from injury. Glasgow Warriors head coach Gregor Townsend said: "We're really looking forward to facing Leinster at a sold-out Scotstoun tomorrow night. "We've had some great battles with them over the years and they have being playing well during the Six Nations window. "They have always set very high standards and continue to deliver a high level of performance, whichever team they put out on the field. "We're delighted to welcome Rory (Clegg) back to the club and he goes straight into the side with Finn (Russell), Duncan (Weir) and Peter (Horne) away with Scotland and Gregor (Hunter) out injured." At Scotstoun Stadium, 7.35pm.
