He commented: "My fitness is getting better with every game. I have had a couple of games down in Newport, which has helped so I am building on my fitness and decision-making.
"I'm feeling quietly confident about myself at the moment. November is the last time that I started, it's been a long old slog but I've got through it and now I am just raring to go."
Looking forward to this weekends match against last years table toppers, Brew added; "Glasgow play with high tempo, always looking for mismatches with backs against forwards and a great offloading game.
"They are a completely different team to three or four years ago but we have often been a thorn in their side, hopefully that will continue."
In addition to Brew there have been three personnel changes to the starting line up. The formation of the backs remains unchanged with the exception of Aled Brew being named in the back three alongside fellow wing Ashton Hewitt and fullback Carl Meyer.
The front row sees one change made to it as hooker Elliot Dee returns to the fold alongside props Boris Stankovich and Brok Harris. The second row remains unchanged with Nick Crosswell and skipper Rynard Landman getting the nod. However the back row sees the inclusion of flankers Lewis Evans and Nic Cudd, who join number 8 Ed Jackson.
The bench sees Rhys Buckley, Ollie Griffiths, Charlie Davies and Nick Scott join Phil Price, Shaun Knight, Matthew Screech and Luc Jones.
