I am another one who is unsure about Martinez, if he is such a fine manager why are Wigan always deep in the mire, admittedly eventually escaping?
Despite the glamour of some of the foreign names, Lambert looks the best fit for me. He has better credentials than Martinez....... taking Norwich from a first day 7-1 home hammering (by his own team!) through 2 promotions to a comfortable mid table Prem finish supercedes the great Wigan escapes imo.
That said, if the rumours are true, I think our new appointment could be decided by whether or not a DoF is appointed. A DoF is not every managers cup of tea......
