Adelaide United coach John Kosmina is unfazed about marquee signing Dario Vidosic's displeasure at being dragged off during their latest A-League loss.
An angry Kosmina pulled Vidosic from Hindmarsh Stadium some 75 minutes into their 2-1 loss to Wellington Phoenix on Friday night in favour of Jacob Melling.
Vidosic brushed Kosmina aside when the coach offered a handshake on the sidelines, the Socceroo clearly unhappy at being substituted for a second match in a row.
Kosmina said Vidosic, who is Adelaide's dead ball specialist, twice ignored team plans against the Phoenix.
"I thought he was great in the first half. He dropped off the pace a bit in the second," Kosmina said.
"And the substitution came because we worked on some set pieces, set pieces that actually work, and he chose the wrong option twice."
Acknowledging Vidosic was unhappy to be replaced, Kosmina said: "I wasn't happy that he didn't hook the right set piece either - especially when the people concerned had talked to him about it and he just went the complete opposite way," he said.
"But it's not about whether Dario is happy or not. It's about what I think is best for the team ... I was unhappy about the set pieces."
Kosmina said Vidosic was subbed in last week's loss to Perth Glory for a fall in work rate.
"We talked about why he got subbed last week - he started dropping off and not winning stuff in midfield or being available in midfield, so we tried to look at a different option," Kosmina said.
