The 30-year-old Norwegian striker scored 10 Premier League goals for Aston Villa last season.
“I have scored a lot of goals and hopefully I will continue to score goals this season,” said Carew.
“I don’t set targets. I just set myself giving 100 per cent and being ready to go for when the games begin.
“The goals normally come by themselves.
“I am doing my best to be fit and ready for when the season starts so I can’t wait to get started again.
“I will do my best to be available for the team and be an important player for the team.
“I am looking forward to the season and I am trying to get myself as fit as possible.”
