Looking to how his side will tackle their league challenge, the Norweigan added: "I don't know any other way than work hard, believe in what you're doing, don't feel sorry for yourself.

"All football clubs at the elite level have systems in place for corporate governance. Cardiff City is no exception. A manager, even in the Premier League, does not go out and "sign" players.
