Nicky Weaver is confident Dundee United have the quality to beat Clydesdale Bank Premier League leaders Celtic on Sunday.
The English goalkeeper saw enough from his team during their 1-1 draw at Parkhead earlier in the season to feel they can use home advantage to go one better.
He said: "When we played Celtic at Parkhead earlier in the season, we drew 1-1 and on another day could have won. They had chances and didn't take them and so did we. To win at places like that, you need a wee bit of luck. So maybe this is the time we'll get it, who knows."
He added: "I think the quality is here at United to get a result against the Old Firm.
"Against Rangers recently, we were a goal down when it got abandoned but it should have been much different.
"I'm not saying they are there for the taking every week but the gap certainly isn't what it used to be."
