Europe next for United
Dundee United guaranteed themselves European football for next season with a 1-0 victory against champions Celtic at Tannadice.
Midfielder Scott Robertson headed the only goal from Keith Dixon's cross to ensure fourth place in the table and involvement in the Europa League. Neighbours St Johnstone can't now possibly catch them after going down 2-0 in the capital to Hearts.
After a slow start the hosts forged ahead midway through the opening half when a short corner allowed Dixon to cross and Robertson met it with a powerful downward header into the net.
Gary Hooper soon had a reply blocked by Dusan Pernis and the Slovakian goalkeeper also parried from Kris Commons, whose dangerous cross almost set up Anthony Stokes just before the break.
Celtic substitute Tony Watt twice threatened upon the restart while Gary Mackay-Steven flashed a shot over at the opposite end and Jon Daly's effort was charged down by Charlie Mulgrew.
The Tangerines had an escape when Emilio Izaguirre's 75th minute cross appeared to find the hand of substitute Keith Watson inside the area before Hooper drove narrowly wide from a sharp angle during the later stages.
