Arsenal captain Cesc Fabregas admits the team needs more strength up forward to match it with the top few teams.
With injuries to key strikers Robin van Persie and Nicklas Bendtner, the Gunners lack a forward who can get beyond the defenders and Fabregas believes the squad needs to potentially bring in players who are a bit different to many others on the playing list.
"Throughout the game (at Manchester City) we had a lot of possession but didn't really have anyone to go in behind defenders apart from Carlos (Vela)," Fabregas said.
"We had a lot of similar players, who like the ball into their feet. Sometimes it's true that you need a different kind of option.
"When a team is better than you, you just have to accept it - as we did against Chelsea - and get ready for the next game.
"Against Chelsea I felt we dominated in the first 40 minutes, albeit without creating too much.
"Perhaps we had the same kind of problem the boys had at City, not really having someone whose game is to go beyond defenders, and we were a little small to fight against them on crosses too.
"Overall I saw a Chelsea team that was normal - but a team that has probably the best striker in the world, and that makes such a difference.
"An average team that has the best striker in the world can always do something, and Didier Drogba makes all the difference to them - without him their team would not be the same.
"In midfield you could see that, if we wanted, they could never take the ball from us. The difference sometimes comes up front - we couldn't take advantage last Sunday while they did.
"They are clinical in front of goal and can score great goals like Drogba did, while maybe attacking-wise we were not at our best.
"We accept, though, that Chelsea are currently the strongest side - they are showing more consistency than us. What is for sure, though, is that we cannot afford any more slip-ups."
