Peter Houston admits Scotland are excited to see Scott Brown in action against Northern Ireland.
Craig Levein's number two was impressed with the Celtic captain's performance during Sunday's 2-2 Scottish Cup draw with Rangers.
Brown, who has seen his international career hampered by injuries, capped a talismanic performance for the Hoops by scoring the equalising goal at Ibrox.
And Houston is hoping the national side finally see the best of Brown in a Scotland jersey, starting with Wednesday's Carling Nations Cup opener.
The Dundee United chief said of Brown: "He's very important. The sad thing is, in the last couple of squads, he had that ankle injury and we have never seen the best of Scott Brown.
"He has been touch and go whether he's fit and, indeed, he's had to come out of a couple of squads.
"Both Craig and I were at the game and I thought it was a very mature and professional performance from Scott Brown.
"He was urging the rest of the Celtic players on and brought Celtic back into a match they were losing.
"Great credit to him, it's always nice to see players who are in the Scotland squad doing particularly well."
Houston, who watched the Old Firm clash alongside manager Levein, was also happy with the efforts of the other Scots involved in the pulsating tie.
"The Rangers lads did well too. Steven Naismith was a right handful in the first half and Allan McGregor's saves speak for themselves," added the 52-year-old.
"Mark Wilson driving forward from the right back area was a threat to Rangers all day and then you've got Kris Commons scoring goals.
"The five players in this squad who played in the Old Firm match, their form is really good and that's pleasing for us."
