Motherwell manager Stuart Kettlewell tells BBC Sportsound: "It went wrong in a number of different ways. We've conceded seven in the last two games. You don't need to search too hard to discover we have a soft centre.
"We're not making good decisions when we're asked questions. We all have to take ownership of it, me more than anyone, but it really frustrates me.
"We must find a solution to conceding such cheap, soft goals. Aberdeen deserved to win the game and we were frankly unacceptable at home.
"We made worst decisions after Aberdeen scored. That comes down to the mental aspects of the game, that discipline. We've shown if we can stay in touching distance, we can get back into it. But for me, it isn't good enough because we have a mountain to climb.
"Simply, we have to better defending our final third of the pitch. Theo Bair's goal is our first attempt on target. We're a far better side than that, and we need to stop haemorrhaging goals."
