Arturo Vidal signs Manchester United shirt during Juventus pre-season tour

Juventus midfielder Arturo Vidal has done little to calm speculation linking him with a move to Manchester United after he was pictured signing a supporter's shirt.

The 27-year-old has been heavily linked with the Red Devils for some time, with recent reports claiming that United are willing to part with Javier Hernandez and £40m cash for the Chilean.

While Vidal has remained quiet of late, the midfielder has been pictured signing a United shirt for fans while in Australia for Juventus's pre-season tour.

Rumours have suggested that United manager Louis van Gaal was concerned about Vidal's knee condition following his surgery prior to the World Cup in Brazil.
