Walters was appointed as the new coach of Catalans Dragons from the 2009 season. He had been linked with the role of head coach at the French Super League team for some time. His first season at Catalans did not start well, with only one win from the club's first 6 matches. However, by the end of his second season with the club, he'd taken them to within one match of the 2009 Super League Grand Final, losing to eventual Champions, Leeds Rhinos.
