Bukayo Saka responded to the challenge set by Arsenal manager Mikel Arteta as he proved a game-changer in the 3-0 Champions League win over Lille.

The England forward has been told he should aim to score "two or three" goals per game - such was his quality and the expectation from his boss.

Saka did not achieve that tally against the French visitors, but shook off illness to come off the bench and assist Eberechi Eze's strike that made it 2-0, before rolling in his side's third goal.

The 25-year-old has now scored four goals in nine games this season and looks to be taking the next step in his evolution as Arsenal's key man.

With the majority of his side's attacking play involving him, he has always been an influential figure. But with opposition defenders doubling up on him and injury issues over the last two seasons, there were doubts over whether Saka could still do what was asked of him in attack or if he had lost a yard of pace.

Arteta has tweaked Saka's positioning this season and, prior to Lille's visit, said it has been done deliberately to get him closer to the goal.

"That is where we need to get him," said the Gunners boss before the game. "And if he misses the chance, so be it. At the end, the more volume we generate, the bigger the probability of him scoring more goals."

Saka's strike against Lille was a confident one-touch finish and came after he missed a late one-on-one opportunity in Saturday's Premier League victory over Leeds.
