Keown believes that the gesture was a clear message to manager Emery.
Ramsey shrugged his shoulders and raised his arms as he celebrated his goal at Craven Cottage.
Arsenal great Martin Keown is fed up of his former side losing their best players to rivals.
The former defender is concerned about Aaron Ramsey's future at the Emirates and believes the Welshman sent a message to Unai Emery with a gesture in his goal celebration on Sunday.
The midfield ace scored the Gunners' third goal as they smashed Fulham 5-1 yesterday afternoon - the north London side's ninth win on the trot.
"Aaron Ramsey sent a clear message as he gestured with his outstretched arms in celebration of his wonderful goal at Craven Cottage," Keown wrote in his Daily Mail column. "This is what you get if you are prepared to pay the money."
He added: "Think of Cesc Fabregas, Robin van Persie and Samir Nasri.
"Too often Arsenal have developed promising players only to sell them. I would be immensely disappointed if Ramsey is allowed to leave."
