Jadon Sancho faces a race against time in order to prove his fitness before a crunch Champions League quarter-final clash against former side Manchester City.
The England winger is struggling with an unspecified muscle injury and has been given permission by Dortmund to fly out to Dubai for some warm weather training in a bid to speed up his recovery.
Sancho is desperate to face his former club, who he left in 2017 for a fee of around £10m in order to move to Germany.
City were desperate to keep Sancho but the winger’s determination to find first team football saw him join Dortmund and he’s now one of the most valued players in Europe, with the German club valuing him at £108m.
Sancho hasn’t featured for Dortmund in close to three weeks and the Athletic claim his chances of playing against City in the first leg are rated at 50%.
City are already favourites to emerge to the last four, where they’ll face the winner of Paris Saint-Germain vs Bayern Munich.
But Sancho’s absence would be a major boost to Pep Guardiola’s chances of taking City to the semi-finals for the first time since 2015.
The club have never reached further than the last four and they’ve only made that stage on one occasion.
