Manly coach Des Hasler has indicated Anthony Watmough is on his last warning with the NRL club, but he's hopeful the repeat offender might have finally learnt his lesson.

Watmough and team-mate Terence Seu Seu were arrested for urinating on a Manly shop front at the weekend, and Hasler let his anger be known when responding to questions about whether the club would wear any more indiscretions from the Test and Origin representative.

"That is a question probably best directed towards the board, but you don't have to be Einstein to work out what the answer might be," he said.

"In Anthony's case it's misdemeanour on misdemeanour on misdemeanour on misdemeanour on misdemeanour and that's something the club will take into its assessment."

However, while slamming Watmough for his stupidity, Hasler is confident reality might now set in for the 27-year-old.

The Test and Origin representative has a growing rap sheet which includes losing his licence for driving at 133km/h in an 80km/h zone earlier this year, and being involved in an altercation with a club sponsor at Manly's 2009 launch.

Watmough and Seu Seu have been stood down from Saturday's clash with Cronulla and fined a week's wages.

Hasler says the clarity of the club's message to Watmough should ensure the in-form second rower can turn over a new leaf.

"I think it has (sunk in)," said Hasler.

"At the moment Anthony is quite genuinely upset about it, he's quite contrite about it, he's embarrassed about it and I think he'd be foolish not to admit that.

"You've got to understand that from a rugby league player's perspective, the greatest travesty they feel about this, apart from letting themselves down and the club down, they've let their team-mates down because they can't play this weekend.

"At the end of the day that's where they're feeling it and that's where they'll feel it the most because they've got to wear the ire of that as well as being embarrassed about the whole situation.

"I applaud the board for the action they took."

Hasler said Watmough's management will become involved in working through the issue.

Seu Seu's future would also be clouded if he found himself in trouble again, as the 23-year-old was sacked from Newcastle in 2007 after being convicted of drink driving.

The coach emphasised that while the incident was far from horrific in the grand scheme of things, it wouldn't be tolerated by the Sea Eagles.

"It's very unfortunate and always untimely. The nature of the offence as far as off-field misbehaviour goes, there are other more serious misdemeanours ... but that doesn't take into account nor disregard the fact that it's bad mannered, it's disrespectful."

Backrow team-mate Glenn Stewart said the club would miss Watmough, but backed the club's young second rower Jamie Buhrer to step up and fill the void.

Hasler said the drama wouldn't be a distraction.

"Not having Anthony Watmough and Terence Seu Seu at Shark Park on Saturday night won't faze this side and that's a great attribute for the side," he said.
