Thompson was not sacked at Celtic he quit according to BBC report

Thompson used to play for Aston Villa and there are rumours that he is going to join up with Lambert. That being the case then that would surely throw doubt on Iain Culverhouse going to Villa.
Not sure if this is significant or not, but Paddy Power had betting for the Norwich job up on their website today, but not long after Thompson story broke the betting on manager is no longer available. Might be nothing but bookies are not daft and if they suspect that an appointment could be imminent or that lots of money are being placed on someone they would suspend the betting. Iain Culverhouse was 18-1, another interesting one was a lot of money was going on Tim Sherwood who had fallen down in the odds. There was a Norwich board where someone posted he would be next manager.
