Gio Reyna out for the season

It was the latest in a series of frustrating injuries for the 19-year-old, whose 2021/22 Bundesliga campaign has been brought to an abrupt end.

Reyna has managed to feature just 10 times in the league this term and has managed only 13 outings as injuries and illness have hampered his progress.

The teenager has the backing of coach Marco Rose to come out of the other side in even better shape, however, with the Dortmund boss predicting that his teenage star will still develop into a world beater.

"Gio will be a world class player," Rose told bundesliga.com after seeing Reyna leave the pitch in tears once again against Stuttgart. "He's a top lad with unbelievable qualities. We'll help him to get properly back on his feet."

Reyna's club have now confirmed that a muscle and tendon issue in the hamstring will rule the USA international out of their remaining top-flight matchdays, and the American will now be setting his sights on getting fit enough for a big year ahead for both club and country.

He will now have the rest of this campaign and the off season to get back to fitness in time for the start of the 2022/23 season and the USMNT's 2022 FIFA World Cup bid in Qatar.
