The hosts were frustrated for much of the match at Emirates Stadium, but Odegaard reacted quickest to slot home on the rebound in the 72nd minute, after Noni Madueke's shot had been saved by Konstantinos Tzolakis.

Arsenal almost had a second when Madueke went through late on, but the winger was tackled by Tzolakis only for the ball to ricochet off Hull's Nobel Mendy and then be cleared off the line by Brooke Norton-Cuffy.

The Gunners' win was their fifth in a row in the league since their 3-0 defeat by Brighton in September - still the only time they have dropped points so far this season.
