Direct Quote from the ever realiable wikipedia:
"On 10th May 2010, Gannon agreed to become the new manager of Oldham Athletic having been approached by and offered the job by Simon Cornball, commencing from 24th May 2010. Oldham had relieved manager Dave Penney earlier in the month. Gannon was a hot favourite for the vacant position along with former Shrewbury, Preston and Rochdale manager; Paul Simpson. Gannon has signed a 3-year deal and will look to build on Latics' past history and fire them back into the Championship, ahead of the proposed new stadium in Failsworth."
