FA Cup giant-killers Reading claimed another Premier League scalp with a 1-0 victory over Burnley in the fourth round on Saturday.
The managerless Championship strugglers had shocked Liverpool in a third round replay at Anfield and they proved that was no fluke thanks to Gylfi Sigurdsson's late winner at the Madejski Stadium.
Sigurdsson, who was only declared fit on the eve of the tie after recovering from a foot injury, produced a cool finish with three minutes left to stun Brian Laws' side.
Burnley had beat Reading in last season's Championship play-off semi-finals but it was the Royals who were the dominant force this time.
Brian McDermott, in temporary charge following the sacking of Brendan Rodgers, would have been encouraged in the early stages when Sigurdsson, who scored a penalty in second-half time added on in the 2-1 win over Liverpool, tested Burnley goalkeeper Brian Jensen from long-range.
Burnley finally sparked into life when Wade Elliot found Graham Alexander and the Scotland midfielder smashed his low shot just wide.
After surviving near-misses, McDermott's men pushed forward again and Jensen tipped over a header from Matthew Mills. Reading's pressure was rewarded in the 87th minute when Andy Griffin's cross picked out Sigurdsson and he pushed his shot into the bottom corner.
Chelsea win without much ado
London:FA Cup holders Chelsea booked their place in the fifth round with a comfortable 2-0 victory over Championship (second division) side Preston North End on Saturday.
The five-times winners took the lead when Nicolas Anelka shot powerfully past keeper Andy Lonergan in the 36th minute before doubling their advantage when Daniel Sturridge finished from close range.
