Shane Warne is convinced Australia will take a specialist spinner into the Boxing Day Test but believes selectors have chosen the wrong man for the job in Michael Beer.
Beer, who has taken 16 first-class wickets at an average of 43 in seven matches, was a shock inclusion in the 12-man squad for the Perth Test and appears likely to play in Melbourne after he was retained in an unchanged squad ahead of the MCG showdown.

But with the Ashes battle delicately poised at 1-1, Warne has called for in-form Nathan Hauritz to be rushed back into the side for the Melbourne and Sydney Tests.

"I think Beer was a horses for courses selection (in Perth)," Warne said. "What's impressed me about Hauritz, he's gone back and taken wickets and made runs.
"As I said before the Test series, I think Hauritz deserves to get the first chance and if he didn't work out, try the next in line.
"So I think it still stands that Hauritz deserves a chance for Melbourne and Sydney."
Hauritz, who was controversially dropped at the expense of Xavier Doherty before the first Test in Brisbane, has taken 19 wickets at 26.78 in six domestic first-class appearances this season.
He is also coming off consecutive centuries with the bat for New South Wales, having smashed 146 against South Australia and 110 not out against Queensland over the past fortnight.
While he does not agree with their current choice, Warne urged selectors not to go into the Melbourne Test without a specialist spinner.
"Historically, (the) Melbourne Test match has always needed a spinner," he explained.
"It's hard to change a winning team but I think a spinner will play.
"The only reason a spinner won't play at the MCG is if Australia want to go with five seamers, including (Shane) Watson."
Warne also played down suggestions that the MCG groundsman has been instructed to spice up the wicket in a bid to ensure a repeat of the Perth result.
"It's a drop-in wicket so there's not much you can do to the wicket," he said. "It will be flat and hard work for the bowlers after the new ball has lost its hardness after 30-35 over mark.
"It's warm in Melbourne and staying like this for the next week or so, there might be a bit more grass on it at the start, but I don't think it's a conspiracy theory."
Meanwhile, injured Australia opener Simon Katich has revealed that he is set to make a shock return in time for the fifth Test in Sydney, increasing the pressure on Phillip Hughes to find form in Melbourne.
Katich damaged his Achilles tendon during the second Test defeat to England in Adelaide and was initially expected to miss the rest of the summer.
But the veteran left-hander has revealed that his comeback plans are ahead of schedule and he may be fit for the Sydney Test, starting on January 3.
Hughes replaced Katich for the Perth Test, but failed to impress.
