The Wales international has had a fruitful start to the campaign, netting eight goals in nine appearances for Arsene Wenger's side already this term.
He continued that run on Saturday by netting in the club's 2-1 victory over Swansea City and his man-of-the-match-performance at the Liberty Stadium helped Arsenal to the top of the Premier League table.
Ramsey came under criticism from certain sections of the club's supporters last season following a series of indifferent displays, when he was utilised in several different positions.
Speaking to Sky Sports, he said: "I've had a bit of stick, particularly last season but I was playing all over the place.
"I'm a central midfielder. I've worked hard. I'm a type who never gives up. I felt like I was definitely improving at the back end of last season.
"I'm in my position now where I've put a load of games together and my quality is just starting to come through."
He added: "Yes (I am surprised). I felt like throughout my career I've been getting into these positions but I've been a bit rash in front of goal.
"Now I feel a lot more composed and confident.
"That's our target (to win the league). We have a lot of quality in the team. We have had a lot of injuries but have managed to dig in and put a few wins together."
