If you want to chart the rise of technology and engineering in football, there are few clearer examples of modernisation than the goalkeeping glove.
Decades ago they were just that, a pair of woollen gloves worn for warmth and grip rather than protection, but they are now complex constructions of foam and plastic as artfully designed as a piece of machinery.
Arsenal goalkeeper Petr Cech has taken another step forward after debuting a truly remarkable pair of gloves during their weekend Premier League visit to Liverpool.
Cech wore a pair of Puma evoDISC gloves - mostly black and white but with a splash of green across the fingers, buts mostly notable for completely covering his wrists and rising halfway up his forearms.
