Former Barcelona head coach Quique Setien believes Lionel Messi is hard to manage, adding that the Argentine's enormous reputation meant he was difficult for the coach to criticise while in charge at Camp Nou.
Setien took over Barca in January after the club sacked Ernesto Valverde, but the ex-Real Betis manager lasted just over six months in the post before he too was relieved of his duties in August.
Barca's stunning 8-2 defeat in the Champions League was the final straw for Setien, who completed a season at Camp Nou that saw the club fail to win a trophy.
