The 30 year old former Chelsea player was subsequently fined two weeks' wages.
And Redknapp said: "Jose made a mistake but it can't go on forever.
"The issue is resolved, he was fined and we've all moved on from it. He's trained hard and is showing the right attitude again.
"There's no question he can play. He's good on the ball.
"I took him with us to Swansea a couple of weeks ago and didn't even put him on the bench. I did that to test his attitude and he was fine."
