Hibernian striker Leigh Griffiths insists lifting the Scottish Cup will cap a remarkable turnaround for the Eater Road club.
Griffiths was part of the team that capitulated in last season's final at Hampden when they were beaten 5-1 by Hearts.
The on-loan Wolves player thought that would be his last chance at securing the Scottish Cup for his boyhood heroes, and he is determined to make the most of his second chance.
He said: "Last season's cup final was supposed to be my last game for the club but that didn't prove to be the case, so who knows what will happen this year?
"But we have got to try and put things right after that game. There are not many teams that get to two cup finals in a row and get beat in both of them.
"We know it will be a monumental task against Celtic. They are a great team with a great squad and a great manager.
"They have won the league by a canter and are no mugs. But we have already beaten them this season and hopefully we can do the same on Sunday.
"I think it is a great achievement by us to get back to the cup final after doing the same last year but that won't mean anything if we lose again."
