Suarez will return to action tonight at Capital One Cup opponents Manchester United.
"Now he comes back we are getting a £50-60million striker back in the team and that is exciting for us," he said.
"This is a player who can come in and make a difference for us.
"All you can do now is judge him by his performances on the field. The measure for Luis now is on the field.
"His way to say sorry or make any contribution back to the supporters is to play with his heart 100 per cent and score goals and make this team successful and I am confident that will happen.
"He can't play any other way."
