Outspoken Adelaide coach John Kosmina is just what the side needs, according to Reds-turned-Melbourne Heart star Michael Marrone.
While Kosmina is rarely far from controversy, the defender said Adelaide's decision to sign him had so far been justified.
Marrone will line up against his old side at AAMI Park on Wednesday night as the Heart attempts their eighth win from nine outings.
Adelaide have failed to live up to general expectations this season and sit second last but are undergoing a mini-revival since Kosmina took over from the sacked Rini Coolen. The Reds have posted a 2-2 draw with Sydney and beat Wellington 2-0 last week.
Marrone, one of the Heart's most durable and versatile assets, said Adelaide under Kosmina would be a team to be wary of.
"He's pretty outspoken, I guess," Marrone said. "He's come out and said some things but, to be fair, so far they've pretty much delivered on them.
"The players have come out quite confidently and are following what he says.
"I reckon they've got a good leader in the coach and they should do well this season."
According to Marrone, the switch in leadership will turn Adelaide into a more dangerous proposition.
"Whenever you change coach, there's a bit of a lift and you saw that," he said.
"They got a good draw against Sydney and last week against Wellington, they played pretty well.
"I think the coach has given them a bit of freedom so I think they are going to be a difficult side, as every side is."
He said Adelaide's aggressive front line would be the potential trouble area for the Heart on Wednesday.
"Having played at Adelaide, you can always look at Serge (Sergio van Dijk), who's been the top goalscorer in a season before.
"He scores some good goals, he's strong and they've got Bruce (Djite) up there as well and Dario (Vidosic), so I think the front three are quite dangerous especially.
"If you want to identify an area, it would be their attack but you've just got to be wary of their flick-ons and such because they've got strong boys up the front," he said.
However, the Heart's unstoppable recent form has meant a major lift in morale and expectations.
"We've definitely got a lot of confidence, we've built up a bit of momentum beating some big teams and coming off a 4-0 win (against Sydney).
"I'm sure we'll go into the game quite confidently."
