At first I assumed this was a wind up but the more I think about this the more it makes sense. He has played at the highest level and under immense pressure. He clearly shows his tactical abilities on a weekly basis, some of the things he spots in games and the analysis of those things is second to none.
I don't think a lack of managerial experience would hinder him to much either, I think his motivational skills coupled with his tactical awareness could serve us well and compensate for the lack of experience, I don't think we should be so quick to palm this off as a daft idea. We need to ensure that we install an experienced assistant who he can bounce ideas off and help with the day to day running of the first team until he had learned the ropes, but I think he could have a big impact where it matters, performances on the pitch.
