Peter Houston insists Dundee United only need to cast their minds back to their early-season setback at the hands on Inverness to know the Highlanders pose a serious threat at Tannadice.
SPL new boys Caley Thistle ran amok 4-0 at Tannadice in an encounter which sent a warning to the rest of the top flight.
And Houston, whose Tangerines side could clinch a top-six place with a victory tomorrow, knows the outcome of their last league clash on Tayside serves as a timely reminder ahead of their Clydesdale Bank meeting.
Houston said: "Inverness are a free-flowing side on their day as we found to our cost earlier in the season.
"They hit top form that day while we were well below par so we don't need any reminding of what they're capable of.
"They have players like Johnny Hayes and Adam Rooney who can really turn it on when they want to."
