Arsenal forward Lucas Perez says he feels "cheated" after the club took his number 9 shirt off him.

The Spaniard lost the shirt number to Alexandre Lacazette, who arrived from Lyon earlier this month.

Perez, who made three starts for the Gunners last season, says the incident is the "last straw" for him and he now wants a transfer to his former club, Deportivo La Coruna, to help keep alive his dream of playing in next year's World Cup.

"They [Arsenal] are not behaving well with me," Perez reportedly told Gunners chief negotiator Dick Law, according to La Voz de Galicia.

"The thing of taking the shirt number without telling me to give it to a companion, it seems to me the last straw.

"I cannot continue this way. I have given everything, but that has not been reciprocated, so I can't stand it any longer. I feel cheated. In February I was not allowed to leave for China with the promise that I would play more and after that I had even fewer opportunities.

"But the shirt number is an ugly gesture. On the trip, Lacazette asked the boss and he accepted. Afterwards, he told me. Last year he [Wenger] told me that he understood that I was upset. I think this season things will get worse, so help me out.

"To play the World Cup. A dream. But for that I have to play and I have to be happy. That's why I want to go back to Coruna."

Perez continued: "I want to leave, to play and be happy.

"Last year I barely had any opportunities and when I had them I took advantage of them. And this season is clearly going to be more of the same.

"I want to fight to go to the national team. I want to play football, but for that I have to leave. And I think that the best place for me is at home, with Depor."
