Arsenal "enquired about the availability" of West Ham's Issa Diop just over three weeks ago, according to a French report.
The 22-year-old had a sublime debut season at the London Stadium, attracting interest from Ole Gunnar Solskjaer's side. However, the fresh information hints that the Gunners also approached the Hammers in an effort to solve their defensive woes.
Foot Mercato claim the Red Devils' verbal offer of just under £50m plus either Phil Jones or Marcos Rojo didn't come close to West Ham's £80m valuation of the defender. Solskjaer soon gave up the chase and turned his attention to Leicester City's Harry Maguire.
