Jonjo Shelvey's extra-time winner sent Charlton through to the fourth round of the FA Youth Cup as they came from behind to eclipse Blackburn Rovers 2-1 at The Valley on Tuesday night.

With the club in the doldrums after the slide into the Coca-Cola Championship relegation zone, Charlton's youngsters put a smile back on the faces of supporters with a hard-earned win.

West Ham manager Gianfranco Zola was among the crowd that watched Charlton dominate for long periods.

They paid the price for failing to convert ample possession into goals when Michael Hall gave Blackburn the lead against the run of play in the 38th minute after Jack Clark's slip played him in.

Charlton, who reached last season's quarter-finals, equalised in the 42nd minute through Sam Long's angled shot.

Charlton won the tie in the 101st minute when the Blackburn defence waited in vain for an offside flag after Steve Lozano-Calderon's pass played in Shelvey who beat Blackburn goalkeeper Bjorn Bussman from close range.

Charlton: Christie; Solly, Mambo, Jenkinson, Clark; Long (O'Shea 79 mins), Stavrinou, Shelvey, Lozano-Calderon (McGinty); Godfrey, Tuna (Perkins 65 mins).Substitutes not used: Lee, Davisson.
