David Jeffrey insists Linfield’s full focus is on progressing in the County Antrim Shield on Tuesday.
The Blues have been paired with Ards in the quarter-final draw.
Niall Currie’s side arrive at Windsor Park looking for some welcome respite from a testing Premiership campaign – Ards currently sit bottom of the table after eight games.
Linfield chief Jeffrey is under no illusions ahead of Tuesday’s showdown, however, insisting the visit of the basement battlers will be a “tough fixture.”
He added: “Games are never, ever easy against Ards, as they showed recently in what was a tough battle in the league game in Ballyclare.
“On Tuesday we will expect something similar.
“This is an important cup tie and it gives us an opportunity to go on a cup run and hopefully, win a trophy.
“It’s vitally important that we make progress in this competition, so we’re looking forward to this game but we know it will be very difficult.”
Linfield will be without suspended duo Aaron Burns and Michael Gault.
Ards boss Currie believes Tuesday’s game presents another chance for his players to prove their character.
“The players have shown enough in the league games so far to give me plenty of encouragement,” he said.
“It has been a tough opening for us but that’s the Premiership.
“Now we have another competition to focus on and we want to do well.”
