Manchester United sell out first batch of £125 Old Trafford turf cubes

Manchester United have sold out the first batch of £125 Old Trafford turf souvenirs. Each 7x7cm square of preserved pitch sits in a glass cube inside a black case. The turf came from this summer's dig-up, the first full strip-back in 14 years. The club calls them 'Old Trafford Turf Cubes'.
