Marc Bartra has stepped up his training with intense sand-based work after being injured in the bomb attack on Borussia Dortmund's team bus last month.
The Spain international was the only player to sustain significant injuries in the blast, which occurred just prior to the Champions League quarter-final first leg with Monaco.
Bartra suffered a fractured right wrist and required surgery to repair the damage, with the procedure going ahead without complications.
The 26-year-old has not played since the incident which resulted in the "longest 15 minutes" of his life, but he is now back in training after returning on Friday.
And on Sunday he posted a video to Twitter showing him taking part in a rigorous thigh workout in the sand, as he steps his comeback up another level.
I keep working to achieve my goal. Have a nice Sunday! Vamos! May 7, 2017
Having originally been ruled out for a month, the former Barcelona defender is expected to feature again for the first team this season, with Dortmund's last game of the campaign coming in the DFB-Pokal final against Eintracht Frankfurt on May 27.
