The Gunners manager has been linked with a host of different players this summer but Wenger has only signed three players so far.
Leicester striker Jamie Vardy rejected the chance to join Arsenal earlier this summer after the Gunners activated his £20m contract release clause, while the Gunners have also failed with a bid for Lyon forward Alexandre Lacazette.
Wenger started with Sanchez up front for the visit of Liverpool last weekend as Arsenal lost 4-3 to Jurgen Klopp’s side, and the Arsenal manager persisted with the Chile international in a central role at King Power Stadium.
And the Gunners boss seemed to drop a major hint that Arsenal will make do with Sanchez in a centre-forward role this season.
“Is Sanchez a long-term solution through the middle? I think yes. I think it is worth to try as he has the quality to go behind,’ Wenger told his pre-match media conference at London Colney.
“On the flanks he uses a lot of energy by chasing back and I would like to use his energy sometimes a bit more efficiently by going behind the defenders as he is a good finisher.
“He has similar qualities to Luis Suarez. He is technically top.
“We have a few strikers who have a chance but if we find the right players we buy. But if you ask people ‘give me names’ they just sit in front of you — it is not that easy.”
Wenger signed Switzerland international Granit Xhaka in a £33m deal from Bundesliga side Borussia Monchengladbach at the start of the summer.
The Arsenal manager has also signed Japanese forward Takuma Asano and Bolton Wanderers defender Rob Holding.
