Benfica and Joel Campbell's agent has slammed Arsenal boss Arsene Wenger.
Wenger blocked the Costa Rica striker from moving to Benfica on deadline day.
He wanted a chance to go out on loan again - after already being farmed out to clubs in France, Spain and Greece since joining the Gunners three years ago - if he was not in Wenger's long term plans for Arsenal, who signed Manchester United forward Danny Welbeck on deadline day..
The 22-year-old's agent, Joaquin Batica, told Portuguese media: "Benfica fought until the last minute to sign Campbell but the operation didn't happen because, in the last hour, Arsenal decided to keep him..
"Wenger says he did not want to sell him. But if he is not in his plans, then why not allow him to leave?"
