VfB Stuttgart have kicked off their preseason with a clear message: they're not giving up on Justin Diehl.

Despite the 20-year-old winger suffering another injury setback, the club is sticking by him, taking him along to their summer training camp.

Diehl, who joined from FC Koln, picked up a ligament injury in his ankle during the 7-1 win over SV Fellbach.

It's the latest in a string of fitness issues that have kept the German-Ghanaian talent from building momentum.
