Liverpool boss Brendan Rodgers says the club has worked closely with Luis Suarez during his ten-match ban.
Rodgers would not confirm whether the Uruguay international had been helped by the club's in-house psychologist Dr Steve Peters in the wake of his misdemeanour, but hinted it had been part of a wide-ranging rehabilitation programme.
"I am not going into too much detail on him but he has had support in every way," said Rodgers.
"It is not just technical and tactical development here, we look at physical elements and how we can improve psychological state. He has worked tirelessly on every aspect.
"He's had a long time to reflect on what has happened but now all that is in the past, the ban is finished and he has suffered because he hasn't been playing.
"Now he is available and we are all delighted he is ready to go again."
But asked whether Suarez had learned his lesson after a second lengthy ban for biting, Rodgers could only say: "We will see, we will see."
