Bukayo Saka came off at half-time of the North London derby, and Mikel Arteta revealed after the game that it’s a hamstring concern.

Three-time Arsenal Player of the Month winner Bukayo Saka has made himself a nailed-on starter for the team at the moment, so it was no surprise to see him involved in a big game against Tottenham Hotspur at the weekend.

Unfortunately, he only lasted the first 45 minutes, coming off at the break for Nicolas Pepe. After the game, Mikel Arteta confirmed it was an injury-related substitution.

“No (it wasn’t tactical), no it was injury,” Arteta said. “We don’t know. He was feeling his hamstring, so we will monitor that.”

The Arsenal fans certainly won’t like hearing about the possibility of a hamstring problem, but there were some positive signs on the day.

Firstly, Saka didn’t pull up at any point during the first half, he completed the 45. After his substitution, he took his spot on the bench, not in the medical rooms. Then, when the game was over, he was on the pitch with his teammates, albeit with a ‘slight limp’.

Hopefully, all that points to a minor problem, not the kind of tear which would require surgery and an extended absence. But we’ll have to wait for Arsenal’s injury update ahead of the Olympiacos clash.
