Manchester United are sweating on Phil Jones' fitness after the defender sustained a foot injury in England training on the eve of the friendly with Germany.
A nagging spell of injuries over recent years looked to have stunted the 25-year-old's progress, yet he has established himself as a key player under Jose Mourinho since returning to the fold in November.
Jones' form led to an international recall for Gareth Southgate's first matches as permanent England manager, although hopes of a first cap since November 2015 have been hit by a training ground incident.
