Arsenal midfielder Cesc Fabregas has pointed to a lack of experience for some of their slip-ups this season.
Defeat to Premier League newcomers Hull and a 1-1 draw at Sunderland - courtesy of the Spaniard's last-gasp equaliser - have seen the Gunners drop four points in their last two matches.
And Fabregas feels the team are suffering from having a squad packed with talented youngsters.
"Our squad is a bit short on numbers and we are very young. Behind me there is Denilson, who is 20, or Alex Song who is 21. Theo Walcott is 19 and Samir Nasri 21," said the 21-year-old.
"It's hard to imagine a midfield where I am the oldest member.
"We find it very hard to win matches, as we do not possess enough experience.
"I scored 13 goals last season but then I had plenty of allies. Tomas Rosicky (injured) was around, Mathieu Flamini (now at Milan) covered every blade of grass and Alexander Hleb (who went to Barcelona in the summer) was like a brother to me out there.
"The team played with a lot of skilful touches, we were as solid as a brick wall and our opponents would not get a look in.
"Now none of those players are in the side and I feel like a rare being. We are more defensive-minded and sturdy as a team but we don't play so much skilful stuff."
