Drogheda United manager Tim Clancy said officials in the First Division are "the most arrogant people I've ever met in football in my life" after his side were edged out by Waterford in the second round of the FAI Cup.

Bastien Hery's crisp fourth-minute strike proved enough to end the Drogs' run in the competition on Friday night and they now turn their attentions to earning an immediate return to the top flight after their relegation last year.

The Louth outfit are fourth and in with a good shout of making the play-offs. Clancy praised his side's performance against the Blues but was left enormously frustrated by the performance of the referee and his assistants. 

"We've scored a couple of 95th-minute equalisers throughout this season but we didn't get to the 95th minute [against Waterford] because, for some reason, the referee gave three minutes added on when there were lads lying down on the ground for over a minute, there were three substitutions," he told RTÉ Sport,s Adrian Eames.

"It's so frustrating with the officials. You can't talk to them, you're not able to talk to the officials, especially the First Division ones.

"The First Division ones, we've had them all season, and they're the most arrogant people I've ever met in football in my life. It's very frustrating. 

"No matter how they perform, if they've an awful game or a very good game, they're out next week. If I have poor performance after poor performance, I get sacked. I lose my job. 

"You try to speak to them, they're standing two yards away from you and they just ignore you. You're not speaking in an angry manner, you're just asking them a question and they completely blank you. They head home in their car and they've no one to answer to. 

"I've got a chairman and a set of fans who put questions to me every time we lose. The referee and the linesman, I know what they're like and I think they're incompetent."

Drogheda host table-toppers UCD on Friday in need of three points to stay in the top four with just three games remaining in the regular season.

Promotion has been the goal year and their young manager, who only retired last autumn, is desperate to keep the dream alive.

"We're right in the mix. We've had a fantastic season in regards to the league.

"We've got a very tough game on Friday against UCD. We can put it up to anyone on our ground. We've got to refocus now."
