Giggs has been assistant/staff for a while now, if he wants to coach his own team he should. But not sure if he does right now, seems content in his current role.
By automatum he should have plenty more experience then Gary right now, who litterally went from being armchair coach commentating games to the hot seat. Ridicolous. While Giggs, tho not the main guy atleast been working for years up close with 3 different coaches now.
