David de Gea sent a message of support to former Manchester United teammate Ander Herrera after the midfielder said he was going through the 'most difficult moment' of his career.
Herrera has played just 11 times for Athletic Bilbao this season after returning to the Basque side last summer. The 33-year-old is yet to complete a full 90 minutes this season and is currently sidelined with a recurrence of a hamstring injury that has kept him out for much of the campaign.
Writing on Instagram, Herrera said: "I'm definitely going through the most difficult time in my career. A little over a year ago I started having recurring muscle issues that I can’t recover from. For someone like me, who has passion for his profession and enjoys every single day of it intensely, it's a very tough thing.
