Gabriel Jesus scored a goal and grabbed an assist to help Arsenal get back to winning ways in the Champions League with victory at Sevilla.

After losing 2-1 to Lens in their previous European outing, the Gunners came through a difficult test against the seven-time Europa League winners.

Gabriel Martinelli got the visitors off and running by marking his Champions League debut with a goal, racing on to Jesus' brilliant ball and rounding the goalkeeper in first-half stoppage time.

Jesus then increased Arsenal's lead early in the second half with a superb strike into the top corner.

Sevilla, backed by a vocal home crowd, got back into the game when Nemanja Gudelj headed in from a set-piece.

From then on, Arsenal had to withstand some pressure as the hosts tried to find an equaliser, and David Raya tipped Mariano's shot on to the crossbar, although it may not have counted because of a possible handball.

Mikel Arteta's side then suffered a late blow as Jesus went off with a suspected hamstring injury, but they held firm to secure a victory that moves them top of Group B.
