Nicklas Bendtner believes he can help get Arsenal's title bid back on track against Chelsea this weekend.
The Danish striker is pushing for a return to the starting line-up after two substitute appearances following a lengthy lay-off.
Bendtner has been out for almost four months after undergoing groin surgery, but he is ready to make an impact in the title run-in.
The 22-year-old believes he has been missed by Arsenal as he feels he offers something different to Arsene Wenger's side.
"When I get back to full strength, I'll be able to make a major impact," Bendtner told the Daily Mirror.
"We have different types of striker who can do different things, and I think the team has missed a type like me."
Bendtner admits Arsenal struggled against Manchester United last time out and he knows they cannot afford to slip up against leaders Chelsea at Stamford Bridge this Sunday, live on Sky Sports 1 &HD1.
"We didn't get going against Manchester United but now we get another chance on Sunday which we must take 100 per cent," added Bendtner.
"We've still got a chance if we win that match. If not? Well, then it's hard to say how it will develop."
FitnessThe Danish international admits he took a gamble with his fitness, but he is confident he is over the injury problems which have blighted his campaign to date.
"I've played two games because there haven't been other strikers available, so we took a bit of a chance with my fitness," noted Bendtner.
"I still feel progress from day to day, so I definitely think that I soon will be completely fit.
"I do feel pain at certain moves and I also feel sore the day after. The groin will get better, and right now it's about finding the right balance regarding training and matches.
"Now there are only four months to the World Cup. The season has gone quickly but the most important thing is that I'm back."
