If it is, then I’d suggest Manchester to Cagliari with Ryanair. They fly Wednesdays and Saturdays. Early morning out & late night back. The stadium is walkable from the city centre/station, as it’s about 3 miles. Ryanair also fly the same route from Stanstead on Tuesdays, Thursdays & Saturdays. Failing that, fly to Alghero from Stanstead, in the north of the island and hire a car.
