Craig Brown has warned his Aberdeen players about the dangers of complacency in Wednesday night's Scottish Communities League Cup clash with Morton.
The Aberdeen boss has seen his side struggle against lower league opposition in the past, having lost to East Fife last season and being forced to a replay by Queen of the South.
And the 72-year-old has urged his squad to learn the lessons of their cup fixtures from last season.
Brown said: "I think we have to be aware of the difficulty we had at Queen of the South last year away from home. So, there will be no complacency.
"We have to be properly focused against Morton or we'll suffer the consequences because obviously having worked at that level, I've got good respect for teams in that league.
"Morton are a team with great tradition and a fighting capacity, so it will be a difficult game."
Aberdeen picked up their first win of the season against St Johnstone on Saturday, thanks to goals from Isaac Osbourne and Johnny Hayes. Under the former Scotland, Preston and Motherwell boss, the Dons have reached three out of the last four semi-finals - only to be defeated on all three occasions at Hampden Park.
Brown is keen to stress the huge significance of a strong cup run at Pittodrie and hopes his men can build on their 2-1 win at McDiarmid Park.
Brown, who is unlikely to risk Russell Anderson after his captain sustained a head wound, said: "We are going there well aware of the importance of the fixture and difficulty of the fixture.
"So don't think for one minute because we had a reasonable result on Saturday that it is automatic that we just turn up and win this one match. We know there is a lot of work to be done."
