Jim Goodwin has called on his Dundee United side to put last week's disappointing defeat by Kilmarnock behind them when they go to Aberdeen on Saturday. United are seventh in the Scottish Premiership after an up-and-down season and were beaten 3-0 by struggling Killie last week off the back of an impressive derby victory. "Last Saturday was a really poor performance from us defensively, which was something that I couldn't foresee before the game given how well we'd played against Dundee," said Goodwin.
