Celtic manager Ronny Deila has insisted that he has no regrets over publicly targeting a domestic treble in his first season as Celtic boss . The Norwegian has set the bar high and riled opponents by repeatedly saying he wants nothing less than a clean sweep . Jock Stein and Martin O ’ Neill are the only Parkhead managers in the club ’ s history to have achieved the feat . Celtic boss Ronny Deila will be hoping to get his hands on the Scottish League Cup this weekend . Deila believes he set his side a realistic target in trying to win a domestic treble . However , Deila defended the treble talk , saying : ‘ What ’ s the worst thing that can happen ? That you don ’ t reach your goals ? ‘ I can say I am happy to win one title this year and reach a goal . But that ’ s boring . You can say something else , but everybody knows the demands of this club . I have said that all season and there is so much hard work and so many games but we have a good chance to win a trophy on Sunday and we have prepared for that. ’ The accepted practice for managers is to try to remove pressure and expectation from the shoulders of their players by playing down trophy talk , but Deila rejects that idea completely . ‘ I learned at Stromsgodset that if you say you are satisfied to be number six then you come sixth . ‘ If you say then that you only want to get to the cup final then you lose the cup final . ‘ You have to say you want to win the league or League Cup . You have to reach for something . It ’ s in your head mentally . Martin O'Neill was the last manager to win the domestic treble at Celtic . ‘ This club is so big and has such a good team that it ’ s possible . If I didn ’ t think it was possible I wouldn ’ t say it . But I know it ’ s possible and that ’ s why I set high goals and make high demands. ’ Desperate to win his first trophy as Celtic manager , Deila has removed a ban on his daughters attending games following some early setbacks when they attended . ‘ I have to be fair with them . They were at the Aberdeen game , away , standing with the supporters . It was a crazy experience for them . They just said that the supporters were crazy and they don ’ t look at the football match . They smelled of smoke and beer . But they will be here on Sunday. ’ Famously pictured removing his clothes on the pitch after Stromsgodset avoided relegation , Deila says he has no plans to embarrass his daughters by repeating the feat if he wins on Sunday . ‘ They are used to it . They ’ ve seen their father doing stupid things before . They are 15 years old and they are probably a little embarrassed about that . ‘ They were there when I took off my clothes after that game . We were sitting on the couch the day after that game , watching it on television . It was not a great sight . If we win on Sunday you can expect a good celebration with the others . I will not take off my clothes. ’ Celtic ’ s rearranged Premiership fixture with Dundee at Dens Park will now be played on April 22 , with a 7.45pm kick-off , because of the Parkhead side ’ s Scottish Cup quarter-final replay .
Ronny Deila said it would be boring to just concentrate on winning the premiership . Celtic beat Dundee United in the Scottish League Cup final on Sunday . Deila is aiming to follow bill foster and Martin O'Neill in the treble .
