Cesc Fabregas has claimed it is "hard to see" Arsenal winning the Premier League or Champions League "in the near future."
The 24-year-old, who left the Emirates last month to return to boyhood club Barcelona in a £35million deal, had gone six years without winning a trophy in north London.
And although the Spain international insists he will always follow the Gunners, he has admitted that uncertainly over the club's short-term plans were a factor in his decision to move to Spain.
He told Sport magazine: "I want to be in a club that is able to win the big titles year after year and I don't see that kind of future for Arsenal.
"I still have many feelings for Arsenal, but I fear that they won't be able to push the other big clubs in England away.
"If you look at the team this season I can't see them finishing in front of teams like Manchester United or [Manchester] City, or Chelsea. There's just too big a difference between the squads.
"I respect that Arsenal don't have the same financial opportunities as the others, but it was part of my decision to leave that I find it hard to see Arsenal winning the Premier League or Champions League in the near future."
He added: "I hope they will replace me and the others that have left with some quality players and maybe they can take Arsenal back to their level as champions."
