Matt backs Tim to stay

Matt McKay insisted we've not seen the last of Tim Cahill in green and gold despite the Socceroo hero hinting he might be close to hanging up his boots.

After picking up a second yellow in the match against the Dutch, Cahill is suspended for the game against Spain, bringing the curtain down on his five-goal, three campaign World Cup career.

Cahill tried to deflect speculation about his future and a possible role at the Asian Cup but later admitted he had had the best Socceroos farewell possible with his superstrike goal.

He said he wanted to keep the focus on the Spain game before making any announcement on his own playing future.

But McKay dismissed the speculation.

"I don't think that will be his last game for the Socceroos," said the midfielder. "I'm positive of it.

"Obviously he's served us so well and he's a leader amongst the boys but for him to have done what he has at these three World Cups is extremely special.

"He'll never forget last night and he'll never forget this World Cup."

McKay paid tribute to Cahill's volleyed wondergoal that went viral around the world within seconds of the ball hitting the back of the net.

"As it floated over, I just thought - please, get a good connection, go in!" said McKay.

"How can you describe it? It's extremely special, for him personally but for us as a team just to have someone of his experience and pedigree to strike it so wonderfully."
