Having qualified for the Champions' League the previous season, Chelsea were bolstered by a £100 million outlay on world-class players, a spree funded by the extensive financial resources of their new owner Roman Abramovich. Manchester United's attack was as strong as ever thanks to free-scoring Ruud van Nistelrooy, but the midfield was weakened following the £25 million pre-season sale of David Beckham to Real Madrid, and the centre of defence suffered a more severe setback after Rio Ferdinand was ruled out for the final four months of the season after being found guilty of the "failure or refusal to take a drugs test". The case of Rio Ferdinand started a debate about punishments relating to drug testing in football, with there being differing views on whether the punishment was too harsh or too lenient.
