Richard Garcia was far from happy with his Perth Glory side as sloppy play at both ends of the pitch resulted in them losing 2-1 against Adelaide United on Sunday.
Glory are priced at 4/1 to finish in the top six of the A-League but they are facing a huge uphill battle to get there after dropping all three points against the Reds.
Glory were back in front of their home fans for the first time in almost four months but they could not celebrate it with a win as goals from Hiroshi Ibusuki and Mo Toure did the damage for Adelaide.
Bruno Fornaroli pulled one back from the penalty spot in the 90th minute but it turned out to be nothing more than a consolation goal.
Adelaide's opening goal came after Glory made a mess of trying to play out from the back. Ibusuki forced a fine save from Liam Reddy and from the corner the Japanese ace headed home.
The injured Reddy had to be replaced by Cameron Cook at half-time and the young stopper was left red faced after a Toure shot squirmed under him and into the goal.
But Garcia was also left fuming as Glory failed to take their chances at the other end, and he says they need to raise their game.
"I'm very disappointed," Garcia told reporters after the game. "We are making the same errors as we did a few weeks ago.
"We keep talking about trying to eliminate individual errors but at both ends of the park we aren't clinical. In and around the box we don't put chances away and then we conceded easy goals."
