Arsenal star Alexis Sanchez was reportedly dumped by his girlfriend Laia Grassi for failing to match up to her expectations in the bedroom.

It appeared that all was not well in the relationship when Sanchez's other half deleted every photo of the footballer from her Instagram account.

Rumours suggested that Grassi called time on their romance after former Miss Chile Camila Andrade claimed that he had been texting her behind his girlfriend's back.

However, according to Chilean media outlet La Cuarta, the 25-year-old was dumped for lasting just three minutes in the bedroom.

Neither Sanchez nor Grassi have publicly commented on their alleged break-up.
