Bukayo Saka needs to protect himself from roughhouse tactics but manager Mikel Arteta warned he must stay within the laws of the game.

Saka reacted angrily to a challenge from Philippe Coutinho during Arsenal's 4-2 win at Aston Villa last weekend, shoving the former Liverpool man before team-mates intervened.

Saka has been involved in 49 Premier League goals for Arsenal (26 goals, 23 assists), and could become the youngest player to reach 50 goal involvements in the competition since Cesc Fabregas in 2008 should he score or assist against Leicester City on Saturday.

With teams increasingly looking to use tough tackling to halt the 21-year-old's sparkling displays, Arteta feels Saka has a right to defend himself.

"The first one who has to protect Bukayo is himself," Arteta said. "There's many ways to do that on a football pitch, within the rules, and he needs to learn and improve that.

"He reacted in a way, but that line is extremely thin and that cannot take him out of his game and lose his focus.

"But he can help that, as well, to have more focus, more determination, more belief for the next action. It's something he needs to do."

Saka is set to make his 32nd Arsenal appearance of the season against Leicester on Saturday, while he also started four of England's five games at the World Cup in Qatar.

Arteta pointed to Saka's mentality as the reason for his ability to play so many matches, explaining: "I really see his determination and where he wants to get to.

"He really wants to get there and have that resilience and that capacity to consistently show a certain level. He has a great physical element to be able to play every three days. Hopefully he can continue to do that."

With his team top of the Premier League table, two points above closest challengers Manchester City with a game in hand on the reigning champions, Arteta is hoping he can repay the Arsenal board's faith in him by delivering the Gunners' first Premier League title since the 2003-04 'Invincibles' campaign.

The former Gunners midfielder has endured rough periods since taking over in 2019, and he is grateful the board have stuck with him.

Asked how significant trust was between ownership and manager, Arteta said: "It's extremely important, obviously. The people you work with need to have faith, but at the same time they have to see every day what you are doing.

"I think it's something that works very close together, and I was lucky to have the people and the ownership we have. They believed we could continue to do the work that we wanted to do and gave me time. Hopefully we can repay that faith."
