Skipper Marcus Kane believes last Saturday's league defeat to Coleraine is a timely wake-up call for title-chasing Glentoran.
Mick McDermott's boys failed to win for only the third time in 19 games, surrendering to a freak Jamie Glackin goal direct from a corner-kick.
The result meant the ambitious east Belfast team, now benefiting from the financial clout of new owner Ali Pour, dropped to third in the Danske Bank Premiership table - four points adrift of leaders Linfield.
But the Glens have the chance to get back on track on Friday night when they roll out the welcome mat for Niall Currie's impressive Carrick Rangers at The Oval.
Kane insists there is no more room for error with the business end of the season approaching.
"Saturday's result was a wake-up call for us," said Kane. "I thought Coleraine were better than us, especially picking up the second ball.
"When Joe Crowe came on, he helped steady the ship a bit. It was a bit of a jolt for us in terms of fighting ability, they (Coleraine) had the fight either side of half-time.
"Perhaps our minds were not right. Maybe we thought it would be easy with the wind behind us.
"Coleraine are good at stretching play and putting the ball in behind us and that's where they got most joy."
Kane reckons his boys now face a must-win scenario on Friday night.
"Carrick have got some great results and have taken some big scalps, so it will be difficult," added Kane.
"We have to get back to the basics. It wasn't our normal 'get over the line' performance at the weekend. Linfield stretched their lead, so looking back a point would have been great (against Coleraine).
"There is a long way to go, 10 games. The lead could change hands a lot from now until the end of the season. There are plenty of points to be won. We now don't worry about other teams - that's all in the past.
"We have to focus on what we do and let them worry about us."
