The Hoops face their Old Firm rivals in the semi-final of the competition this weekend.
St Johnstone midfielder Liam Craig has explained that he desperately wants Celtic to clinch the Scottish Cup trophy as it will allow for one more Scottish Premiership side to earn a Europa League qualifying spot for next season, the Evening Times reports.
The Hoops face Rangers in the semi-final on Sunday while Hibernian and Dundee United will contest the other semi-final one day earlier.
And with two of the remaining four sides currently playing in the Scottish Championship while Dundee United are bottom of the top tier, Craig suggested that those chasing fourth spot in the league will want Celtic to win the competition.
"Motherwell, ourselves and Ross County will all believe they can finish fourth and we'll all want Celtic to win the Scottish Cup," he told the Evening Times.
"As a player, you love these European adventures. Just look at what this club has achieved with its trips to Rosenburg, Luzern and even Alashkert last season.
"They were great trips for the fans and we want another sample of that next season.
"Hopefully Celtic can win the Scottish Cup and we can hold up our end of the bargain by finishing fourth."
With the split now in effect, St Johnstone know that they now only need to see off competition from the likes of Motherwell and Ross if they hope to secure continental football for their fifth campaign in a row.
And with the fact that Ronny Deila's men closing in on another league title means that they can give more attention to turning it into another league and cup double, Craig will be confident that the Bhoys can do his side a favour by coming out victorious at Hampden Park.
