The bruising nature of Premier League centre-backs means the impish Russian has little chance as a target man, and he is growing frustrated.
"If Arsenal want to become champions, how can they select Arshavin as centre forward?' he said, as reported by the Daily Mail.
"I am 173cm [5ft 7in] and it suits me, but next to the big centre halves of [Manchester] United it is very difficult to fight for the ball, especially in the air."
The midfielder, usually used playing behind the front two, has been forced into a position change thanks to injuries to Arsenal's leading forwards.
"It's from frustration," Arshavin said of his makeshift role. 'Van Persie is injured and unlikely to play again this season.
"Eduardo is injured too, but he may be ready to face Chelsea. We are in a difficult situation when it comes to recruiting players."
Arshavin admitted third place might be all the Gunners can hope for.
"Third place is where we stand today, and that is already a great success for Arsenal when you take into account the class of our 11 players," he added.
"Of course, we try to win every match, but class is class."
Arsenal face a do-or-die encounter with leaders Chelsea on Saturday, hoping to get revenge for a 3-0 defeat at the Emirates in November.
And to keep out Chelsea's star attackers, Arshavin thinks left-back Gael Clichy will need to up his game from the 3-1 demolition by Manchester United last weekend, where Nani tormented the Frenchman all afternoon.
"In training it is very difficult for me to beat Clichy, but Nani made all the play through him," Arshavin added.
