Aberdeen manager Derek McInnes insists his team must maintain their recent high standards for the remainder of the campaign to avoid serious disappointment.
The Dons have already won the League Cup this season following a penalty shoot-out victory over Inverness Caley at Celtic Park in March.
Aberdeen are also leading the race for second place in the Scottish Premiership ahead of Motherwell and Dundee United.
But McInnes reckons defeat to St Johnstone in Sunday's Scottish Cup semi-final at Ibrox will put a dampener on the campaign for Aberdeen.
"At the minute it has been a good season, but how it is really described will be determined over the next five, six, seven games, hopefully," he said.
"I think if we can get to another cup final and be 90 minutes away from lifting the trophy, if we can get among the European spots, especially where we've come from in recent seasons, it would be a very significant season and one that will live long in the memory.
"As much as there is still a lot to play, there is still a lot we can miss out on, and I don't think we'll be totally satisfied if the League Cup win is the only thing we're really pleased about.
"So with that in mind, we've got five important league games and a semi-final next up, so we'll do our upmost to finish the season strongly as possible."
McInnes insists he does not expect a repeat of this season's League Cup semi-final with St Johnstone when the Dons won 4-0 at Tynecastle.
"I thought the scoreline flattered us but at the same time because we were that clinical, because we carried that threat of real pace on the day, we caused them problems," McInnes added.
"But they are also capable of causing us problems and we are well aware of that. They've got some good players. They've got a good manager and a good work ethic."
St Johnstone v Aberdeen is live on Sky Sports 2 from 12.30pm on Sunday.
