Central Coast Mariners skipper Alex Wilkinson was frustrated after his side's 1-1 draw with Adelaide United yesterday.

The Mariners were inconsistent in their performance but managed to fight until the end and force a draw when Matt Simon equalised in the 84th minute and although a point is better than none, Wilkinson said it was testing at times.

"It's very frustrating, it's like we had two different teams out there today. In that first half we were lethargic and weren't doing the work for each other on or off the ball," Wilkinson said.

But the defender, who scored the winner in the season opener against Melbourne Heart last week, said the team's fighting spirit did enough to earn them a point.

"In the end though 1-nil down with ten minutes to go, and we managed to get back into it That's one of our strong traits, and we've got to be happy with that," he added.
