Adelaide United's Cassio says he is prepared to give his all for the club as he gets set to return from a troublesome calf injury.

The Brazilian import has been out of the first team for about a month and following a spat with coach Aurelio Vidmar, it looked his career with the Reds could have been over a few weeks ago.

But Cassio is now determined to make every post a winner with his adopted club and help push them up the table.

"I am ready to go and training well. If I play I expect it to be for 90 minutes. I don't go out on the pitch expecting to just last for 45 minutes," said Cassio.

"I spoke with Viddie and agreed I'd tell him straight away if I am having any difficulties.

"I will give everything I can for the team.

"We have to change our placing in the league."

Cassio added that he did not have a problem with where Vidmar plays him and insisted he was over his feelings of animosity from a few weeks back.

"I am fine and have confidence wherever I play. Everything that happened is in the past," said Cassio, who expects to fulfil his contract and "remain with United until 2011".

"Everyone has problems at some stage and I did a few weeks ago but that was it.

"There are no issues. I have good relations with everyone.

"Usually when I have something to say I just say it but then move on."
