Arsenal captain Martin Odegaard is hoping Bukayo Saka's injury isn't serious.
Saka broke down during defeat at Champions League opponents Lens last night.
"I think every team in the world would miss Bukayo, but we have to see what happens in the next few days," said Odegaard. "Hopefully, it's not too bad and he'll be ready for Sunday.
"Last night was not the best game for us. We have to keep going, we have to learn from it and make sure we bounce back in the next game.
"We have to move on, that's all we can do now. It's a massive game coming up and everyone is excited. We have to look forward, make sure we're ready on Sunday."
