Mikel Arteta has hailed Bukayo Saka's maturity and labelled what the Arsenal winger is producing as "unbelievable".

Saka produced two assists and scored Arsenal's third goal in the Gunners' 3-1 comeback win over Southampton on Saturday.

The England international leads the way for chances created (27), big chances created (12), assists (seven) and expected assists (3.16) in the Premier League this season, while only Manchester City's Bernardo Silva (19) has crafted more opportunities from open play than Saka (17).

With Martin Odegaard out injured, Saka has also taken on the responsibility of captain, and Arteta is thrilled with what the 23-year-old is delivering.

"That's the maturity and that's the steps that players have to do. He has been long enough in the team now, he has the right to have that role," said the Arsenal manager, as quoted by Sky Sports.

"He believes in that, that he has the capacity to change games, to decide games, like many other players, and he wants to be at the top.

"I think it's another step ahead, and it's what he wants.

"Do it at home, do it away, do it in big games, in the not-so-big games, and when the team needs it, not when it's 3-0. That is what defines a top, top player.

"What he's doing at his age is unbelievable. We have many examples of that as well."

Saka's next goal in the Premier League will be his 50th for Arsenal.

Since his debut in late 2018, only Pierre-Emerick Aubameyang (50) has netted more goals in the competition for the Gunners than Saka (49).

Indeed, in that time, Saka leads Arsenal for chances created (320), big chances created (54) and assists (42), having played 177 times in the top flight, 35 times more than any other Gunners player.
