Australia drop Neill, Bresciano for Ecuador friendly

The friendly in London on March 5 is the last chance Postecoglou has to cast an eye over players before naming a provisional squad for the World Cup in Brazil, and he opted for plenty of fresh faces.
"The squad to face Ecuador represents the first steps in what I believe is the building of the next golden generation for Australian football, acknowledging there is a need to balance experimentation and experience to achieve this," he said.
"The Ecuador match gives this group of players an opportunity to stake a claim for the World Cup.
"They have been rewarded for playing consistent and strong football and shows that age and limited international experience are not barriers to opportunity."
The biggest omission was 35-year-old defender Neill, who is nearing 100 caps for his country having made his debut in 1996. Tim Cahill is expected to be skipper.
Since leaving Turkish club Galatasaray in 2011, Neill has spent time with the likes of Al Jazira, Al Wasl and Sydney FC and Postecoglou had said he must be playing full-time football to be considered.
Neill this week joined English Championship club Watford on a free transfer.
The coach made no specific mention of Neill, but said "selection in the final squad for the World Cup is still very much an open door".
The squad contains four uncapped players, five plying their trade in the domestic A-League and three brought back after missing the 1-0 win over Costa Rica last November.
Curtis Good, Chris Herd, Massimo Luongo, and Ben Halloran, will all have the opportunity to make their Socceroo debut.
