Two goals from Tim Cahill and one apiece from Harry Kewell and Brett Holman were enough to get the Roos past India.

"In particular, in the first half, we played very well, " he told Fox Sports at full-time. "It was very difficult to start a tournament against an opponent, no matter who it is, is fresh, they are ambitious.

"You have to break them down and that is what happened. We played tactically a very disciplined attacking style of football and we scored three.

"It probably could have been a bit more but I am still pleased with the performance of all. We don't want to ask for too much..."

In the second half, the game descended into a training match run out for the Roos when it lost impetus after the final round of substitutions saw Scott McDonald, Nathan Burns and Matt McKay introduced.

Osieck added: "It is important to start the tournament well and considering the short period of our preparation, it was very important to have a game like that to work on tactical stuff under match conditions.

"From here, we can build for the next games we have to play. I'm going to take the opportunity to take a look at the Korea team. It is definitely going to be a tougher test.

"A victory like today will build up some confidence and give us the right mindset to take to the game and be successful as well."
