The Wales international is yet to register a goal for either club or country so far this term, and the usually reliable midfielder has endured a barren spell which stretches back to a 3-1 win over Hull City back in May.
Ramsey netted 13 times in the 2013-14 campaign before registering 10 strikes for Arsene Wenger's men last term, but he is without a goal in a dozen games so far this season.
Speaking ahead of Sunday's visit from Manchester United, the Welshman aired his frustration behind his inability to find the net, and also conceded that he has no idea when his last goal was.
The Mirror quotes Ramsey as saying: “I don’t know how long it’s been since my last goal. I just know I haven’t got off the mark yet this season, which I’m disappointed with."
Ramsey reserved a word of praise for teammate Alexis Sanchez, who struck a hat-trick as the Gunners beat high-flying Leicester City 5-2 last Saturday.
“It wasn’t just [Sanchez]. There are a few other players – myself included – who are a bit frustrated not to get a goal, but I’m delighted for him that he’s finally got off the mark. As soon as the first one goes in [for the Chilean], two more fly in straight away! Hopefully now he’s in a good place where he can just go from strength to strength.
“That’s how it goes. You get frustrated and then all of a sudden a few games down the line one comes and the next thing you know you’re scoring on a regular basis again. Hopefully I can be there soon as well.”
Wenger's men will be looking to bounce back in style when they host Manchester United at the Emirates on Sunday following their disappointing Champions League reverse to Olympiakos at home on Tuesday.
