Another injury to worry about: Milos Ninkovic left Saturday night's game with an ankle injury. Credit:Getty Images "The first 30 minutes was poor and I don't know where it came from. That's the hardest thing," he said. "We had a good week at training, we got four boys back from suspension. "That first 30 minutes was what made it really difficult for ourselves and after that we were probably the better side and we did well in the second half but you can't do that [concede a big start] in the A-League." When asked if he could work out why his defence had become so porous of late, Arnold was at a complete loss. "If you can find out, can you please tell me – because it's something I'm dumbfounded with," he said.

"Because, at the end of the day, we don't practice that, and we know that Wellington try to get the ball in between the lines, in the back of the midfield, and you have to try and stop that. "There was two warning signs before [the first goal] that, which [Vedran] Janjetovic saved. But we didn't heed the warning." Compounding the result was the sight of Milos Ninkovic going down early in the match with what appears to be a season-ending ankle injury, meaning they'll be without him and captain Alex Brosque, who has a torn hamstring, for the run home. "[It's] probably season over. To lose Ninkovic, whose been outstanding this year, is a tough blow for both competitions – the A-League, but also the Champions League," Arnold said. "We're not having much luck, over the whole season. Losing Alex Brosque, obviously, is a blow, and I threw a lot of faith in Alex Brosque at the start of the season to be our number nine and I think he's played eight games this season."
