Second Division Wigan pulled off another sensational Worthington Cup shock after they beat Premiership side Manchester City.

Paul Jewell's men had already claimed the scalp of West Brom in the previous round.

And Neil Roberts' first-half strike proved the difference on this occasion as City were unable to break down a resolute Wigan defence.

Wigan goalkeeper John Filan produced two excellent saves in the closing stages to keep City at bay.

But the result was no less than Wigan deserved as they stretched their unbeaten run to 15 games in all competitions and booked themselves a place in the last 16.

City manager Kevin Keegan had emphasised the importance of a good cup run for the club prior to this Worthington Cup tie.

And he signalled his intent by fielding a strong side, including striker Nicolas Anelka.

Wigan matched their Premiership opponents in the opening period, but in truth it was a first half high on endeavour yet lacking any real quality.

One of the few highlights was provided by City defender Sun Jihai.

His jinking run left the Wigan defence flat-footed as he passed to Ali Bernabia, but City's midfield maestro could not supply the finish.

City were then forced into a double defensive substitution as Steve Howie and then Sylvain Distin limped off injured.

Sun fouled Nathan Ellington on the edge of the area, allowing Keegan to bring on Kevin Horlock for Distin.

Andy Liddell whipped in a dangerous free-kick which the new-look City defence failed to clear and Roberts pounced from close range to give Wigan a deserved lead.

With City having already made two changes in the first half, Keegan introduced Darren Huckerby after the interval in an attempt to inject some urgency into his side.

But Huckerby's pace could not rectify City's abject passing or their general shortcomings.
