Inverness Caledonian Thistle's Bobby Mann is not daunted by facing Uefa Cup semi-finalists as he believes his side are even better than the one that rocked Celtic three years ago.
Caley Thistle's victory inspired one of the most famous headlines
The 29-year-old defender is one of only five players left from the team that beat the
Glasgow side 3-1 in February 2000 to signal the end of John Barnes' reign at Celtic Park.
That result, one of the biggest ever upsets in Scottish football, led to the equally famous newspaper headline "Super Caley go ballistic, Celtic are atrocious".
And the Highland club have continued their improvement since then and this season have made their first concerted challenge for the Division One title.
Their consistency has deserted them in recent weeks under new manager John Robertson following Steve Paterson's move to Aberdeen in December.
But, looking forward to the Sunday evening tie, Mann said: "We are a better side now than we were three years ago, but the problem is so are they.
Cup upsets happen all the time
Caley Thistle forward Liam Keogh
"At Parkhead, we caught them on a great night for us and a very bad one for
them. Things just seemed to fall perfectly for us.
"They have faced top sides like Blackburn, Liverpool, Celta Vigo and
Stuttgart this season and have done well against them.
"They are getting stronger all the time, so their confidence must be sky-high.
"We know we are in for a difficult game, but we just have to hope that we give a good account of ourselves.
Steve Paterson led Caley Thistle to the win at Celtic Park
"We always create chances for our strikers and we are at home, so, if we can shut them out at the other end, then we will give ourselves a chance."
Caley Thistle forward Liam Keogh endured that defeat three years ago as a Celtic youth.
Now the 21-year-old is hoping to experience joy against his former club and said optimistically: "Cup upsets happen in football all the time."
