Munster legend Keith Wood says Reds bosses should give Johann van Graan an ultimatum to either change his approach or leave six months ahead of schedule.
Wood was disgusted by the lack of ambition that he saw from his former club in last Saturday's 10-8 loss at Connacht.
And, speaking on Off The Ball, he claimed that young players such as Craig Casey and Gavin Coombes are being "ruined" by the conservative tactics employed.
"There's no point in talking about Munster's attack, that doesn't exist at the present moment in time,” said Wood.
"I think we're beginning to ruin some of the players, I'm finding it incredibly hard to watch.
"If there's a bit of a disruption, then I'd rather the coaches went than stay and play that level of turgid nonsense."
With head coach van Graan confirmed as Bath's new supremo from the summer, and senior coach Stephen Larkham returning to the Brumbies when his contract expires at the end of the season, Wood predicts that a shake-up is exactly what the province needs now.
"He's gone, he's going," said Wood of van Graan.
"When I look at Munster at the moment, it's almost about grinding out the win.
"The discipline was poor, the energy... I don't know what's going in the coaching set-up or the training, but if that is the extent of the first, big game of the Christmas and the extent of the energy then something isn't right.
"Whether it's because the players think the coach is gone or the coach isn't getting his message across, there isn't going to be wholesale changes in the players.
"The rumour mill is that a lot of the South African guys that have come over with him will go and I don't know if that's true either, I hope it isn't.
"But, you're looking at the game and saying 'go, play at pace'.
"The manner of which Munster played at the weekend is the manner of the way they played against Leinster in the last few years and Saracens before that, it's to have a limited style to stay in the game.
"It hasn't been good enough further down the line, it's now not good enough for a team that isn't at the top of the tree.
"You say to Van Graan, 'are you willing to stop slowing it down?'
"Change the thinking or change the coach. I don't know if they will.
"It's not something that usually happens, we're looking at a lot of young Munster players coming into the system, they need to be able to play and need to be able to grow in the game."
Wood expressed a desire to Larkham, though he is also leaving, taking charge of team affairs.
"I'd say, 'Stephen, there's an expectation that you can make players play if you're given the temporary head coach role to the end of the season, can you make that happen? See if you can change Munster into something that can excite a crowd',” Wood said.
"I like Van Graan, I get on fine with him, but his comment afterwards that this was a derby and it was going to be very tough, that's a lovely comment if you've shown some effort, but there was no effort shown really, no thinking put into that game.
"I look at the team, I look at a lot of the young guys who have got a chance... I'm a bit disappointed with the selection as well, I don't think we should be chopping and changing as much as we do.
"The idea of having to give players match-time, no. Getting the team to play properly is the most important thing at the moment and I don't know that Munster are doing that.
"Look, I think it's very hard. There's an awful lot of really good players there, I don't think they're world beaters.
"But whatever new coach comes into Munster needs to be a coach that looks at the players they have at their disposal and has to improve them, to play a style that suits them.
"At the present moment in time I don't know if either of those things are true."
