FA Cup heroics from Peterborough, Arsenal march on

Third tier Peterborough United produced the performance of the FA Cup fourth round when they twice came from behind in the dying minutes to earn a 2-2 draw at Premier League West Bromwich Albion on Saturday.

On a day when the big guns largely extinguished the hopes of the dreaming underdogs, the League One side proved indomitable after Saido Berahino had twice put Albion ahead.

Peterborough's heroes were Shaquile Coulthirst, who first equalised in the 79th minute, and Jon Taylor, who answered Berahino's second goal with just four minutes left to earn his side a lucrative replay at their London Road home.

Portsmouth, a club who have fallen on hard times in the fourth tier of the English game, briefly sniffed a sensation before Premier League Bournemouth battled from behind to win 2-1 thanks to an 83rd-minute Marc Pugh winner.

Arsenal maintained their push towards winning the Cup for a third successive year as Alexis Sanchez, back in the starting line-up after injury, scored the winner in a 2-1 victory over Championship side Burnley at the Emirates Stadium.

Some of the other favourites also earned a fifth-round tie with some comfort.

Tottenham Hotspur accounted for third tier Colchester United 4-1 with a double from Nacer Chadli and Manchester City piled further misery on struggling Aston Villa with a 4-0 win, adorned by a hat-trick from teenage prospect Kelechi Iheanacho.

Oxford United, another fourth-tier side, could not repeat their third round giant-killing of Premier League Swansea City as they went down 3-0 at home to Championship Blackburn Rovers.
