turn the screw

Arsenal's dominance was reflected in a flurry of goals before half-time – three in six minutes: first, Podolski turned the screw with a peach of a free-kick; then Gervinho accelerated on to Mikel Arteta's beautifully crafted pass and beat Davis at his near post with conviction; and finally Southampton's defence unspooled completely when Gervinho broke to release Gibbs, whose return ball cannoned off Nathaniel Clyne for Southampton's second own goal of a sobering afternoon.
