I work as a Physiologist within Sport Science and whilst we did rush Gbamin through (the dangers of buying late) as the other poster said it's a worrying injury. It's also the sixth thigh based injury he has had within the last few years. I noticed straight away with him that (imo) he is a bit of an odd build about him, him is quite big and bulky on top but with these long wiry legs and a bit of an odd running style. It's not by any means a career threatening injury (not given the resources in football) but it can easily have lasting results in the form of restricted movements and the fact that your brain just will not let you do stuff in the way you could before because it just thinks things will go wrong automatically.
