But there was some intellectual firepower backing up this stuff. It wasn’t all tosh. A 2002 press release from the University of Sheffield headlined ‘BEND IT LIKE BECKHAM’ is a prime example. It quoted Dr Matt Carré of the University of Sheffield Sports Engineering Research Group, who explained that they had developed a wind tunnel technique which had enabled them to analyse in detail, for example, David Beckham’s sensational goal against Greece in the 2002 World Cup qualifiers. Dr Carré said:

We know that the shot left Beckham’s foot at 80mph from 27 metres out, moved laterally over two metres during its flight due to the amount of spin applied and during the last half of its flight suddenly slowed to 42mph, dipping into the top corner of the goal. The sudden deceleration happens at the moment when the airflow pattern around the ball changes (from turbulent to laminar mode), increasing drag by more than a hundred per cent. This crucial airflow transition is affected both by the velocity and spinning rate of the ball and by its surface seam pattern. So, working from instinct and practice, Beckham was instinctively applying some very sophisticated physics calculations in scoring that great goal.
