Arsenal will attempt to sign Thomas Lemar again in the future.
Arsene Wenger confirmed Arsenal bid €100 million for Lemar on deadline day.
"€100m for Lemar? Yes all true, I wanted him," Wenger said. "He decided to stay at Monaco."
Wenger then added: "We will come back for him."
Wenger said Lemar turned down the move after Arsenal agreed upon a fee with Monaco.
