Crusaders boss Stephen Baxter says keeping Glentoran strikers Curtis Allen and Robbie McDaid quiet is key to winning the League Cup quarter-final.
Baxter's side travel to the Oval while Ards host Ballymena United in Tuesday night's two last-eight games.
"Curtis Allen and Robbie McDaid are very lively in attack so you have to be aware of their threat," he said.
"I saw Glentoran recently and they were worthy winners against Coleraine - they are a good side with quality players."
Premiership champions Crusaders beat the Glens 3-0 at Seaview in their first meeting of the season last month.
Baxter's men have won their last two matches to move into the title picture while the Glens have slipped down the standings after five defeats in their last six league games.
Sky Blues flying high
Glentoran's latest loss came at the hands of in-form Ballymena, who won 1-0 on Saturday to remain third in the standings.
Ards may be struggling at the foot of the table but Sky Blues boss David Jeffrey expects it to be a tough test for last season's beaten finalists.
"We played Ards in Bangor in August and they were by far the superior team in the first half," he said.
"A better second half saw us eventually triumph on the day but if they had taken their chances we probably wouldn't have won.
"We won the competition in my first full season at Ballymena and got to the final last season.
"However, we didn't perform against Dungannon in the decider and we would like to get back there and make up for that disappointment.
"In order to progress we must overcome a resolute, well-organised and good footballing side in Ards."
The other quarter-finals see Cliftonville entertain holders Dungannon Swifts on 20 November and Linfield are away to Championship side Portadown on 4 December.
