Arsenal have made formal contact with Wolfsburg over the possibility of making Ricardo Rodriguez their second summer signing, 90min.com has reported.
The Gunners have been told they must trigger the player's release clause by July 1 if they want to sign him.
They were also linked with the Switzerland international during last summer's transfer window.
Meanwhile, Wolfsburg sporting director Klaus Allofs has confirmed that the fee of the Swiss international will go up after the end of June.
"We are on the alert and we are prepared [to listen to offers]," Allofs told Kicker.
"They [Ricardo Rodriguez and Luiz Gustavo's fees] will not get cheaper, rather the opposite, [should other sides fail to trigger their respective release clauses].
"There is enough time to come to a decision during that period."
