The Scarlets have recorded only one loss in their last seven league contests their only home defeat in the championship being to Leinster in September.
The home side knows it faces strong opposition with Glasgow in third position in the league on – with the Scarlets in sixth.
The Scarlets field a strong and attacking back line with George North and Scottish international Sean Lamont on the wings, Jonathan Davies and Scott Williams in midfield wth Rhys Priestland at outside half and Gareth Davies at scrum-half.
Hooker Matthew Rees leads his Scarlets side with Iestyn Thomas returning to the front row and Deacon Manu starting at tighthead with plenty of power on the bench with replacement forwards Ken Owens, Rhys Thomas, Josh Turnbull, Aaron Shingler and Rhodri Jones.
Scarlets Head of Rugby Nigel Davies said: “We said before Christmas that the trio of games against the Ospreys, Dragons and Glasgow were crucial in terms of our league position and aspirations to challenge for a play-off place. It’s a massive game for us this weekend to stay in contention and good to see that we’ll have another big home crowd to support us and spur the boys on.
“Our two team performances over the festive season produced competitive wins against the Ospreys and Dragons which was a very positive statement from both a Scarlets and national perspective showing the commitment to develop Welsh talent.
“The selections and performances showed that we have strength in depth building here and there’s some fierce competition now to get and hold onto the Scarlets shirt across the 15.
“Glasgow have really progressed this season, they are a well-coached side and play a good brand of rugby and certainly deserve the success they’ve had so far.”
