Wojciech Szczesny believes the flurry of festive fixtures are responsible for the Premier League's spate of shock results.
The top six have all dropped points over the Christmas and New Year period with Manchester United beaten by Blackburn, Manchester City slipping up at Sunderland and Chelsea losing to Aston Villa.
Arsenal had made up ground on all of their top-six rivals before succumbing to a 2-1 defeat at Fulham on Monday and Szczesny believes a run of four games in 12 days took its toll on Arsène Wenger's side.
"The fixtures come thick and fast and players get tired and these kinds of results can happen," he told Arsenal Player. "We were hoping to take advantage of that but we failed to do so.
"It was very confusing [against Fulham] because for 85 minutes I thought we defended really well with 11 men and they never really looked like scoring. Then when we had the ten men they put a lot of pressure on us and they looked very dangerous.
"We played 48 hours before and we went down to ten men and so there were probably some tired legs. I think we should still have kept the concentration, kept the focus and we would have been fine. We are disappointed with the result but hopefully we can recover as soon as possible."
The game at Craven Cottage included two big refereeing calls with Johan Djourou sent off for a second bookable offence and Gervinho denied a penalty after a trip from former Gunner Philippe Senderos.
"Johan says he barely touched him," said Szczesny. "The guy seemed to go down easily, plus I had the ball in my hands already, which doesn't help. But after Johan got sent off it was very difficult for us.
"And from what the lads said in the dressing room it wasn't a penalty claim [for Gervinho], it was just a clear penalty."
