Gilberto: Gunners can’t afford to slip up against Charlton

GILBERTO is warning Arsenal cannot afford to slip up against Charlton tonight if they want to stay on course for a Champions League place.

The Gunners have dropped down from third spot to fifth after their shock 1-0 defeat at Sheffield United on Saturday — when victories for Liverpool and Bolton helped them leapfrog the north Londoners.

The likes of Portsmouth and Tottenham are also vying for a top-four spot this time round — leaving Arsenal’s stand-in captain Gilberto in no doubt about how costly it could be to have another off-day against one of the Premiership’s lesser lights.
