"I still think Andy Carroll will come good. He didn't have a pre-season last year. He never really got his act together because of that and I think you'll see a much better player next season," he told the Daily Mirror.
"It was a fair decision [leaving Carroll out] based on what he did last season. He didn't do enough when he came back.
"There were a few games he was devastating in - against Swansea he set up both of Kevin Nolan's goals - but he knows he didn't do enough to play for England.
"I'm pleased he wasn't with England this summer. His time will come."
