Jack Ross took full responsibility after Dundee United were thrashed 3-0 at home to St Mirren as he and his players were showered boos as the final whistle.
The result makes it two wins in two for the Buddies while United have now conceded 14 goals in the last three games, including seven in the previous two Premiership games. And Ross' men trudged off at Tannadice amid a disastrous run of results since that first leg win over AZ Alkmaar.
Ross believes something has got to change. He told BBC Sportsound: "[That was] Way, way, way below acceptable in terms of performance and the manner of the goals that we conceded. I think that’s the big thing about it. We didn’t do anything near enough to win, we deservedly got beat and deserve all the criticism that will follow and fall on my shoulders because it was not good enough in all aspects of play. At the moment we’re not giving ourselves a platform in terms of defending properly as a whole team, we’re not doing that.
