At the time, Chelsea were comfortably sitting at the top of the Premier League table, 5 points ahead of eventual runners-ups, Manchester City.
They had also finished at the top of their UEFA Champions League group stage and were in the semi-finals of the Football League Cup.
On the other hand, Bradford City were in their second-consecutive season in EFL League One, after winning the 2013 Football League Two play-off Final against Northampton Town.
Bradford City's Portuguese winger, Filipe Morais joined Chelsea's academy in 2003 when he was 16.
Mourinho promoted him to the first team at the start of the 2005–06 season.
He would've made his senior debut for them that season, but didn't make any appearances as he was loaned out to MK Dons for most of the season.
Billy Knott also spent time in Chelsea's academy, from 2007 to 2010, before transferring to Sunderland.

During a press conference before the match, Chelsea manager, José Mourinho, said that if they were to lose to Bradford City that afternoon, it will be a "big disgrace" due to the fact that the Blues were one of the stronger sides in England at the time.
