The Gunners midfielder admits it hurts the players to fall 12 points behind the Premier League leaders after losing four of their first seven games.
Wales captain Ramsey said: "It's been a difficult time for my club. It's been quite frustrating so far with the problems that have been happening in the last few games.
"We have not produced results we're capable of."
Ramsey added: "Arsenal are one of the top clubs in England and where we are at the moment is totally unacceptable."
