Champions Celtic fell to a first league defeat in six matches as Scott Robertson's header was enough to give Dundee United a 1-0 win at Tannadice yesterday.
Neil Lennon's side, who had last lost in the league in March, came into the match on a run of five successive wins without conceding a goal. The hosts went ahead from their first notable attack against a much-changed Celtic XI, Robertson powering home from Paul Dixon's cross.
Celtic were denied a penalty when Keith Watson handled, leaving Lennon, who is serving a touchline ban for confronting a referee over a penalty decision in last month's loss to Hearts, to call for consistency from officials. "Maybe I should ring John Fleming [the Scottish FA head of referee development] and ask him what is the difference," he said. "If they want to give them against us, then that one today has to be a penalty as well. You've got to be consistent.
"I am going to get accused of being a sore loser or blaming referees but it's not the point, what I want is an answer and I don't feel I get them."
In yesterday's other game, Hearts beat St Johnstone 2-0, goals from Rudi Skacel and Andy Webster.
