As soon as it became clear that Gabriel Jesus had injured his knee, back in December when he was playing at the World Cup, Arsenal had only one immediate priority: getting him on a flight to London. Jesus was far away in Qatar, with the Brazil squad, and the striker was in a state of considerable emotional distress.

To be ruled out of a World Cup is a painful blow for any player, of any country. But it was particularly galling for Jesus, who had been deeply affected by his struggles at the 2018 tournament and was itching to shine on the global stage. For him, Qatar represented a personal mission as well as a collective pursuit of glory.
