Barry Johnston insists there is 'no cause for alarm' at Linfield despite the Blues falling short in this season's title race.
The Blues missed out on making it five championships on the bounce as Larne emerged from the pack to win their first-ever Gibson Cup.
Johnston believes a marathon schedule took its toll on David Healy's men, who will play their 60th game of the season with Saturday's trip to Clifftonville.

He also believes the transition to full-time football also played a part in Linfield's struggles, as did the lack of a star striker.
But despite he club's disappointment this season, Johnston "guarantees" they will bounce back with a bang next term.
He said: "I don't understand how someone like David Healy is coming under pressure.
"How long did it take the Larne players to adjust to full-time football? The first season is a buzz where the adrenalin sees you through, and then the body gives in.
"Tiredness and fatigue kicks in. Linfield went through that transition last season, and they have had two or three times as many injuries this year than last.
"They have been in before any other club this year, because of the European campaign. They have played 60-odd games, on top of last season's games.
"And I am sure the players are fed up looking at each other. They just want a break and want the season to finish."
One area Johnston believes Linfield will address this summer is their strike-force.
Eetu Vertainen is the club's top scorer this season, the Finnish striker bagging 19 goals for the Blues.
Robbie McDaid failed to fire in his debut season before picking up a serious injury, while Chris McKee and Ethan Devine chipped in with single figure goals during the course of the campaign.
Healy attempted top bolster his attacking options earlier this year with the short-term signing of Northern Ireland front-man Kyle Lafferty, but the 35-year-old has endured a torrid time in the Irish Premiership.
The former Rangers man has failed to score in eight appearances and is unlikely to remain at Windsor beyond the summer.
"I know people have asked questions about goalscorers, but you try and find them. We were so lucky at Cliftonville that we had Joe Gormley for so many years," Johnston added.
"And then Ryan Curran came along, another goalscorer.
"This year Lee Bonis has come out of his shell and scored goals for Larne, and he could go to England this summer. They also have Paul O'Neill and Andy Ryan who hit the ground running.
"Linfield have just been unlucky in the transfer market. They gambled big on Kyle (Lafferty) which didn't work out.
"But around the rest of the pitch, midfield and defence, Linfield are not a million miles away. It is just up top.
"The goalkeeper is good, defence and midfield. And they are all good ages.
"Some of the older lads will need nurtured a bit more, but they have young players coming through.
"Linfield aren't a million miles off, but they will look for a forward. But that's all they will be looking for.
"I can't see them looking too much further, and they will be competitive next season. I guarantee it."
