Kosmina walks out on Adelaide
Adelaide United have suffered a massive blow with coach John Kosmina resigning from his role, citing a 'lack of trust' with certain figures at the club.
The Reds are currently sitting fourth in the A-League but have spent the majority of the season in the top two.
"Before last weekend we had been first or second in the league and were recognised as a good football team. However, apart from survival, I can see no clear direction," said Kosmina.
"There is no vision. Decision-making at management level is reactive and impulsive at best, and there is no consistency in managerial procedure.
"There is far too much whispering in corridors and around corners. I feel sorry for (co-owner) Rob Gerrard, and I also feel for directors Richard Noble and Phil Lounder - people I trust.
"But I simply cannot, and will not, work in an environment which otherwise lacks trust."
Kosmina first coached Adelaide in the NSL in 2003, maintaining the role for the inaugural A-League season in 2005, and led the Reds to the premiership and grand final in 2007.
The former Australia captain resigned shortly after losing the 2007 grand final 6-0 to Melbourne Victory but returned to coach his hometown club after Adelaide parted ways with Rini Coolen in 2011.
