Arsenal boss Mikel Arteta described the Christmas schedule as "absolutely crazy" after losing Bukayo Saka to injury against Crystal Palace. The Spaniard saw his side win 5-1 at Selhurst Park, but the win was soured by his key forward limping off after 15 minutes.
Saka, 23, appeared to get treatment on his knee before limping down the tunnel.
And afterwards, Arteta refused to speculate on the severity of the knock before taking aim at league organisers.
"I don't know how serious (it is)," said Arteta. "He had to come off because he felt something, it's not good news obviously. So we wait and see now."
And despite the ruthless nature of his team's performance, Arteta demanded his players keep their levels up for the remainder of the season. Asked about their title chances, he replied: "We want it, but we have to show it for 10 months.
"The demands are incredible, to play every two or three days, it's absolutely crazy. Unfortunately today we lost some players. It's happening to every team."
