Arsene Wenger effectively surrendered the Premier League title to Chelsea after watching Arsenal throw away the lead to lose 2-1 at Swansea City on Sunday.
The result meant Arsenal slipped to sixth place in the table, below Swansea and 12 points behind leaders Chelsea, who go into the international break unbeaten.
"At the moment Chelsea are on course to get 100 points this season," said Wenger.
"If you look at the number of points they have today, if they keep that up nobody will catch them, that's for sure."
Arsenal at the weekend once again failed to show the spirit to drag them through a game that they should have won in south Wales.
"I think it's a game that we were quite in control of at 1-0 up. I felt that we allowed them back into the game by losing some challenges in the middle of the park that you cannot afford to lose.
"It's unfortunate to lose a game like that, but we were not rigorous until the end. We produced a decent performance for 75 minutes, but you have to last 90 minutes," Wenger said.
Swansea manager Garry Monk was rewarded for making two attacking substitutions in the game, bringing on Modou Barrow and match-winner Bafetimbi Gomis.
"I wanted to seize the initiative, especially after we equalised with the free kick. I just felt confident," he said.
"We prepared for the best Arsenal and, at times, I think we saw that. I thought we managed them very well and we showed the inner belief we have in the squad."
