Thierry Henry at Manchester United training ground

Arsenal legend Thierry Henry was a surprise guest at Manchester United's training ground on Wednesday. 

United strike sensation Marcus Rashford posted a photo of him with Henry on his Instagram page, taken at Carrington. 

The purpose of Henry's visit to United's training base is unclear although, to speculate, it would be typical of manager Jose Mourinho to try and get one over on rival Arsene Wenger, by offering Henry a role.
