This is a vibrant side boasting skill, speed and fortitude in abundance: Dave Martin and Lewis Grabban, both discarded by local rivals Crystal Palace, have been revelations, contributing 10 goals between them; defensive lynchpin Zak Whitbread is attracting interest from West Brom and loan signings have been integrated without the team missing a beat. Yet Millwall's makeover extends far beyond their football. Off the field, there have been changes. Suddenly, as if inspired by their side's feel-good style of play, fans are making The Den a place of smiles, not scowls.
