Arsenal boss Mikel Arteta says Bukayo Saka must adjust the way he plays to protect himself better.
Ahead of Saturday's visit to Leicester, where Arsenal can stretch their lead to five points, Arteta suggested Saka relishes the physical "challenge" posed by defenders. But the manager reminded the 21-year-old of the dangers of losing his temper.
"There's many ways to (protect yourself) 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 the focus," Arteta said.
"But he can help that, as well, to have more focus, more determination, more belief for the next action. So it's something he needs to do."
Arteta added: "He needs to learn when to take certain balls, what to do with that ball, how to use his body, when to jump if you ask him how it used to be when he was 10, 11, 12, 13, 14 it isn't very different. Wingers and talented players get kicked and fouled and get the demand to win games and that is the chance he has, that is his role in the team."
Saka has won 40 fouls in the Premier League this season but they have resulted in only four bookings. Saka himself has been carded five times.
"It is normal creative players want to be stopped," Arteta said. "It's a challenge he's going to face with every opponent in front of him and he wants to win that challenge."
The manager added: "I'm sure refs want to protect every game and individuals in the best possible way. There is a lot of focus now on Bukayo, and we need to keep that in mind as a team with the plans that we put together, understanding what the opponents are doing. But for sure referees have their responsibilities and they have to do their jobs."
