Adelaide United seeks path to redemption Senior Adelaide United players say they haven't bought into former coach John Kosmina's spat with management. Adelaide United defender Nigel Boogaard says football managers "come and go." CENTRAL defender Nigel Boogaard says rebounding from the club's "pants-down" moment against Western Sydney Wanderers in December presents a greater hurdle than the resignation of coach John Kosmina. Kosmina on Monday suddenly resigned after 14 months as head coach in his second stint at Hindmarsh - but the players have moved on. Atoning against a Western Sydney side that embarrassed the Reds 6-1 in Parramatta six weeks ago - and has jumped into third spot - can be the only focus. "Definitely it is a motivation, that is a pants-down moment," said Boogaard. It is not a good situation and no one likes that in sport. We didn't step up like we wanted to in Gosford so, hopefully, we can have a big turnaround and push forward to the finals. Managers "come and go" in the professional game, leaving little room for sentimentality, Boogaard explained. I didn't see it coming but it is like that around the world. It is not our job to look into the reasons why, just to get on with the job," said Boogaard of Kosmina, who left wanting a two-year extension to his handshake deal at Hindmarsh. He has his reasons, it is up to him. Whether it is right or wrong, it is his decision. I think if you read too much into what is going on off the field it can consume you. Boogaard said he hadn't heard from Kosmina since the tumultuous departure, while the squad was now intent on impressing interim coach Michael Valkanis. Training was slick despite wet conditions yesterday at Santos Stadium, with central defender Jon McKain - stripped of the captaincy and regular spot by Kosmina - pressing for inclusion. "We are looking forward to the challenge and obviously Michael Valkanis is here for the rest of the season and with every new coach intensity lifts at training," said Boogaard. Each coach has their own style and philosophies. Having reached the Asian Champions League quarter-finals last year, the fourth-ranked Reds are targeting the top-two finish that guarantees a record fifth return to the prestigious tournament. "We are looking forward to the challenge of cementing a top-two spot to get back in Asia where the club belongs," said Boogaard. Of the three seasons I have been here, this is a great opportunity for us to go on and do well. Bruce Djite (groin) is a chance to gain a bench slot while magical Marcelo Carrusca is expected to start in his second game back from an adductor strain. Jeronimo's suspension means either Carrusca or Dario Vidosic could become the front man while Valkanis will be tempted to play with two holding midfielders after the last result against Tony Popovic's organised Wanderers.
