After seemingly nailing down his place as second choice Munster scrum-half behind Conor Murray last season, Cathal Sheridan has found himself battling it out with Duncan Williams again this year.
The Sligo native struggled to get back into the squad after his return from a broken arm last season but tonight against the Newport Gwent Dragons, he has an ideal opportunity to prove to the new coaching staff what he is capable of.
"There's a lot of competition but it's healthy," he said. "Even with the internationals away, there's so many lads pushing for places here. It's a big chance for guys who haven't played a lot of rugby this year.
"If you make a mistake you may not get back in for the guts of a year but you'll have no one to blame but yourself."
Munster are boosted by the return of Ireland duo Ian Keatley and Robin Copeland - both of whom featured from the bench against Georgia last weekend.
JJ Hanrahan starts at full-back while new South African signing Pat Howard is on the bench.
The Dragons are looking to end a three-game losing streak in the Pro12 but they did beat Munster at Rodney Parade last year and Sheridan is fully aware of the threat that they carry.
"It's one of the toughest grounds in the league to go and get a win," he said
