I don't think Garner would return with Clem in charge from what I have heard about how he left us.
Even from Garners own words in the interview with Hawes, he left because of changes behind the scenes he wasn't happy with (see Chorley exit time), so its difficult to see him returning.
However, Garners stock is pretty low right now, sacked by Charlton, and then by Colchester so i think he struggles to get another league job, so i guess its possible he lowers his standards to secure one possibly?
Despite his 'success' he never really built that relationship with the fans and thats down to his own personality but also the tendancy to play a brand of tippy tappy football that a significant number of the town faithfull lambast. So if it were to happen i don't think Clem would get much credit for bringing him back.
Someone on here pointed out that our new assistant worked with him and Russell and WBA, not sure how true that is? Is this another Lewis Ward type arrangement. We want him but the terms of his Colchester seperation see us waiting until the end of the season to do it? I doubt it personally.
Personally his reluctance to move away from 5-3-2 annoyed me for a lot of the season, and it amused me our run at the end of the season to get to the playoffs was because we played 433 finally, with Barry/Davison/McKirdy up top.
I don't think bringing him back is the way to go sadly.
