The Arsenal boss insisted during the summer the Costa Rica forward was part of his plans this season, but has only afforded him 16 minutes of Premier League football thus far
The Costa Rica international garnered many admirers when an impressive loan spell at Olympiakos lead to a series of eye-catching performances at the World Cup.
Wenger has since maintained that Campbell would be in his first-team plans this season - even reiterating that the 22-year-old would not be allowed to leave on loan in the final days of the transfer window.
Arsenal since signed striker Danny Welbeck in a last-gasp €20 million deadline day deal and campbell's agent, Joaquim Batica, has questioned Wenger's motives for his client after rejecting an offer from Benfica.
"Benfica fought until the last minute to sign Campbell but the move didn’t happen because, in the last hour, Arsenal decided to keep him," Batica is quoted as saying by O Jogo.
"Wenger says he did not want to sell him. But if he is not in his plans, then why not allow him to leave?”
Campbell has been afforded just 16 minutes of Premier League football so far this season.
