Adam Hollioake says the decision to drop Steven Finn for Chris Tremlett is a brave move, but ultimately a good one for England.
The former England all-rounder was speaking after the squad was named for the third Ashes Test and while many predicted James Taylor would be included as cover for the injured Kevin Pietersen, few anticipated Tremlett and Monty Panesar being brought in at the expense of Finn and Graham Onions.
The news will come as a huge blow to Finn, who was in the team for the first match of the Ashes series, but Hollioake believes it's a sign of England's selectors refusing to get complacent.
He told Sky Sports News: "The big shock is Chris Tremlett. He's obviously a wonderful bowler and there's nothing against him, but Finn first of all got dropped out of the side and now he's been dropped out of the squad.
"Tremlett from my old side Surrey has been bowling well recently and England are confident at the moment. They're making big decisions and changes and that's very brave of them.
"It just shows you the strength of England that they've won the first two Tests and yet they are still making changes and still looking to improve.
"Often you see winning sides sitting back and not making those tough decisions, but I think it's a good thing that they are looking to improve.
"Tremlett is a wonderful bowler, another tall bowler, and they've made some real tough decisions. That's going to be a good thing for them."
Finn (0-37) was afforded just 10 overs in the second innings at Trent Bridge as Australia came just 15 runs short of a dramatic victory and Hollioake says the tourists were eager to take him on.
He says Tremlett is a similar type of bowler, but if he plays at Old Trafford then he has the confidence and the form to make his mark.
He added: "He's a big guy. I don't know what they're feeding these young guys today, but they are massive human beings!
"Tremlett is probably one of the biggest guys I've ever seen; he's solid as well as tall. He hits the bat hard, he'll run in and bowl into the wicket
"He's an experienced player. He's been unfortunate with injuries throughout his career, but when he's fit he is one of the best guys around.
"He'd be a tough guy to target. Australia did target Finn in the first Test, but Tremlett's an experienced guy now who has been around a while. He'll be pretty much up for whatever comes his way.
"I think he's a really good selection."
Hollioake also said there was sound logic concerning the inclusion of Panesar on an Old Trafford pitch that may suit two spinners, rather than relying on the inexperienced Joe Root.
He added: "They must think it's going to spin. I was up in Manchester for a Twenty20 game recently and it spun a little bit then.
"Joe Root did well in the second Test and took a couple of wickets bowling spin. But it's a little bit different bowling part-time and picking up a couple of wickets than bowling as a front-line spinner with the expectation of taking wickets.
"Monty Panesar is the stand-out second-best spinner in the country, so if you were going to pick a second spinner then Panesar would be the obvious choice.
"He's a good bowler. He maybe hasn't improved as he would have liked, but I know Monty and he's a good guy and he'll be working hard and wanting to put that right.
"He maybe hasn't improved as much as he would like, but he's also had limited opportunities with Swann doing so well."
