Manager Arsene Wenger has insisted that he is prepared to make a marquee signing this summer.

Arsenal appear to have missed out on Napoli’s Gonzalo Higuain after Italian giants Juventus agreed a £79million deal for the prolific striker.

But a report by Eurosport claimed that Leicester sensation Riyad Mahrez is likely to join Arsenal for £42million and that the deal is set to happen “imminently”.

Wenger told ESPN FC: “We are very active, and if we find the right candidates we will spend big money. We have already spent big.”

Arsenal’s chief executive Ivan Gazidis previously stated that the transfer window was not the most important time for the club, but Wenger has assured fans that they will continue to search for new additions this summer.

The Londoners have already signed Switzerland international Granit Xhaka this summer for around £34million, making him the second most expensive player in the club’s history.

Xhaka is second only to Mesut Ozil, who joined the Gunners in a £40million deal from Real Madrid in the summer of 2013.

Wenger has also added two youngsters to his squad with Japanese forward Takuma Asano and recently Bolton defender Rob Holding joining on a long-term contract.

Despite Arsenal’s capture of the experienced midfielder Xhaka they will remain in the transfer market for a big signing.

Former Chelsea goalkeeper Petr Cech was the only big signing made by Wenger during last summer for £10million and it remains unclear whether a world-class player will move to the Emirates in this window.

In other Arsenal transfer news, former captain Tony Adams has rejected the chance to coach the Under 18s.
