The Latics started the game without a recognised striker and allowed Rotherham, without a win in six games, to dominate proceedings.
Soft goals apart the Latics put in a very poor performance and new manager Malky Mackay has focussed his attentions on the need to 'work hard' to take things forward.
Speaking to the club's official website after the game Mackay said: “I thought we lost a truly awful goal in the first half and that set us back after having two or three early forays on their goal. To lose that was a real blow just before half time.
The result left Mackay with one point from his first five games as Latics manager and teh defeat was the worst possible start to a triple header of fixtures against three Yorkshire based sides in and around ourselves in the relegation battle.
Next up is the trip to Leeds United on Boxing Day before Sheffield Wednesday visit he DW Stadium on Decembr 30th.
