Munster head coach Johann van Graan says the evolution of their game plan is still a "work in progress", despite some positive signs in their United Rugby Championship win against the Cell C Sharks.

Van Graan's side ran in six tries during the routine 42-17 win at Thomond Park, but there were hints of an expansion in the style of play, with more of a willingness to widen the pitch and bring the likes of Andrew Conway and Simon Zebo into the game more.

It was a growth in the plan that the head coach had spoken about in pre-season, and while his centre Chris Farrell was keen to stress they're only making minor changes to the plan, Van Graan says he was pleased with the attacking intent on display at Thomond Park on Saturday.

"Yeah, look, there were a few new nuances in there in our attack," he said.

"It was a very good night and we executed some, some we didn't execute and there were perfect conditions out there.

"You've got to also then look at the fact that a lot of guys had their first game of the season and some new combinations that will take time.

"But certainly a willingness to play and make the right decision and even that last play is a very good example of some of things that we want to do.

"But you’ve got to look at what’s in front of you and even Goggy’s little kick there in behind was a good decision.

"You know, one or two opportunities that we missed out there that we’ll go and review but certainly if we can play on nights like this hopefully we’ll make sure that we win games."

While Munster's starting team for their opening URC win contained a spine of experience in the form of Dave Kilcoyne, Niall Scannell, John Ryan, Peter O'Mahony and Simon Zebo, there's a growing feeling that the younger members of the squad are putting their own stamp on the squad.

Craig Casey was magnificent in his man-of-the-match display, Gavin Coombes bludgeoned himself over for a brace of tries, Fineen Wycherley has added lineout calling to his repertoire in the last year, while Thomas Ahern and Keynan Knox (above) impressed off the bench on Saturday, in what's set to be a big season for both.

The pressure on those younger players to step up is amplified when you factor in the players Munster lost in the off-season; CJ Stander, Billy Holland, Tommy O'Donnell and James Cronin to name just a few.

Van Graan says he has full belief that their academy graduates can provide the spine of the squad for the next generation.

"I think we have got a good balance in our group. Obviously we lost a lot of experience, more than 1,200 caps in terms of players departing, quality players," he said.

"The reason we did that is because we believe in the next layer of guys coming in. A good mix between experience and youth."
