The Arsenal hierarchy are set to meet owner Stan Kroenke in the coming weeks as the Gunners transfer chiefs battle to get their business done on a meagre budget.
The likes of Mesut Ozil, Henrikh Mkhitaryan and Shkodran Mustafi are all available for transfer but the players, many of whom rank among Arsenal's highest earners, have attracted little interest. The Gunners would be able to top up their budget by selling marquee players but are reluctant to do so.
Arsenal's leaders - including head of football Raul Sanllehi - will fly out to the US in the next week. Emery's side are in action in Denver, where Kroenke Sports & Entertainment (KSE) owns an NBA franchise, and Los Angeles, the home of the Rams' NFL team, another of the KSE stable of sporting organisations.
Talks with Kroenke could see a request for the owner to personally invest his own funds to add to Arsenal's transfer budget and allow them to pursue the likes of Zaha. If the 71-year-old were to agree it would represent a major change of approach at the Emirates Stadium.
