Arsenal are weighing up matching the buyout clause of Wolfsburg fullback Ricardo Rodriguez.
Wolfsburg sporting director Klaus Allofs insists the player's price will inflate after the date, despite Rodriguez being keen to leave the Bundesliga club.
Allofs told Kicker: “We are on the alert and we are prepared. They will not get cheaper, rather the opposite."
The 23-year-old has been linked with a move to the Emirates as Arsene Wenger looks to strengthen his defence.
