Arshavin plays his part in Gunners' FA Cup quarter final victory
But it was the visitors, Hull, who opened the scoring, as Nick Barmby's shot took a deflection – and looped into the goal 13 minutes into the game.
Arsenal's response didn't come until 74 minutes in. Bentner's cross fell to Arshavin, who teed up Robin Van Persie to make it 1-1.
And just ten minutes later, William Gallas came up with the winning goal despite more than a strong suggestion of offside.
His header earned the Gunners a 2-1 win that sets them up for a semi-final clash against London rivals Chelsea.
