Derby County's star striker Patrick Agyemang is making strides in his recovery from a serious Achilles injury. The forward is currently working with Roba Physical Therapy and Wellness clinic in Connecticut, as he begins the long road back from a ruptured Achilles. Agyemang is not expected back until Christmas after suffering the injury in a win over Stoke in April. In a video posted on Roba's Instagram account, the former Charlotte FC striker has been putting in the work while his USA international team-mates prepare for the World Cup. Underneath the video of Agyemang in rehab, Roba posted: 'An unstoppable comeback is in the making.' Agyemang issued an update himself at the beginning of June when he spoke for the first time about his injury which ruled him out of the World Cup this summer. But he is determined that when he is back fit, he will carry on where he left off after scoring 10 goals for Derby last season.
