London - Arsenal reached the FA Cup semi-final as they came from behind Tuesday to beat Hull City 2-1.
Veteran forward Nick Barmby gave Hull a first-half lead, only for Robin van Persie to level with 17 minutes remaining.
With seven minutes to go, William Gallas headed into an empty net to give Arsenal the win, despite appearing to be offside.
Hull had controlled the early stages, but Arsenal battled back and were the dominant side in the second half.
The opener came for Hull after 13 minutes. Andy Dawson's lofted ball found Barmby, who hit the dropping ball first time. It struck the thigh of Johan Djourou, looped up over Lukasz Fabianski and just under the bar.
