Whoever is taking over Wenger has a tough job rebuilding the squad. Mertesacker retiring, no more Sanchez, Cech poor, their only class players being PEA and Ozil. Spurs being a class team and stepping out of the shadow rubbing salt to wound.
Gunn seems to have ties to Norwich, having come through their academy and his father being a former player and manager. Maybe those are factors in them giving him a good chance.
