Assistant boss Tiernan Lynch believes Glentoran have to inflict an early blow on Armagh City’s Irish Cup hopes at the Oval on Saturday.
The two sides are preparing to renew rivalries in this sixth round replay – following a 1-1 draw at Holm Park on February 8.
“It is going to be another tough game, and we are under no illusions,” Lynch said.
“We had a tough game at their ground a couple of weeks back, on a quick artificial surface that we weren’t used to.
“But we had our chances that day, and Curtis Allen missed a penalty to make it 2-0. I think if that had gone in it would have been a different game.
“We know we have to start quickly and get on top of Armagh at the Oval. I believe if we can get an early goal then it will break their spirit.
“At the end of the day we are a Premiership side playing Championship 2 opposition, and these are the games we really have to be winning.
“If we work hard and get the ball down and play, then I would be confident of progressing to the next round.”
Glentoran have been hit by news that midfielder Marcus Kane faces an extended spell on the sidelines with a knee injury.
Kane picked up the knock in reserve team action last week.
“It is a major blow for us, especially as we also have David Howland out long-term,” Lynch said.
“But we have Kym Nelson there and Niall Henderson, so it opens the door for someone else to come in and claim the spot.”
