Perth Glory coach Steve McMahon's patience with veteran Glory marquee signing Brian Deane is starting to run thin ahead of this Saturday's crucial A-League encounter with the Newcastle Jets at EnergyAustralia Stadium.
The 37-year-old English striker, drafted in by McMahon before the start of the season, has started in all of the Glory's games so far this season but has failed to impress.
McMahon revealed he has not been happy with Deane's form so far.
"I'd be lying if I said I was pleased with him," McMahon said.
"If he came out and said he was happy with his performance, then I'd be a bit baffled.
"He's been disappointing by his own standards and I'm not going to hide behind that.
"I've spoken to Brian briefly, he's disappointed with the situation and with his form (and) he knows he can get better, so there's still a long way to go yet and he still has a lot to offer this football team."
Deane arrived in Perth a week before the Glory's season-opening loss to Central Coast Mariners and figured in that match for the whole 90 minutes.
He played five full matches before being substituted last week and McMahon admits he is tempted to rest him.
"It's a legitimate option to rest him yes, it's something that's crossed my mind, it's something that I will be thinking about and it's something that I will have a chat with him about."
McMahon will have a lot of thinking to do on the trip to the steel city, like who will fill in for midfielder Simon Colosimo who is on international duty with Australia.
Stephen McMahon Jr has been called in to the travelling squad and he will be up against Nick Ward to partner Billy Celeski in the middle of the park.
"Wardy (Ward), Stevey (McMahon Jnr) and Billy will be contesting (those central midfield) positions, it's a matter of working out do we go with two attacking players away from home or do we go with two defensive players," the former Liverpool player said.
"(Newcastle) have got plenty of injuries, they'll be quite vulnerable and that will come into my judgment of who I will play and who I won't play."
Glory striker Damian Mori, who was signed a four-week deal, will join the team in Newcastle.
Meanwhile, Newcastle will be without the suspended Nick Carle, striker Ante Milicic and Richard Johnson, who are out with hamstring and thigh injuries respectively, and Jade North - who is on international duty.
