For nine years Patrick Marber has grappled with writer’s block (which by some miracle doesn’t affect his screenplay work), but the pipes are now ungummed and wallop! his new bolus of creativity splatters across the Dorfman stage. It’s a wordy three-hander set in the swamp of non-league football. Marber brilliantly captures the grubbiness and despairing optimism of ageing sportsmen who inhabit a golden age that never was.
