So there's a theory doing the rounds (albeit on Reddit) that the issue with Tanguy is he has anterior pelvic tilt (or ATP for short), which means he has poor posture because his body's forcing him to have poor posture and his is the reason why he's susceptible to injury as his hips stack up into his lower back and cause his spine to arch and also put strain on his hamstrings and groin, meaning that in profile you look like this

Now remember that photo of him in training that did the rounds last week, which had the usual reactionaries saying he'd been at the pies

More importantly, when you see Tanguy run he certainly looks like the right-hand picture in the diagram - and I have to say I know what a misaligned spine and hips can do, thanks to what could be referred to as a cataclysmic even in my lower back at the start of December putting him hips out of alignment and causing my spine to find a new home in my sciatic nerve, which in turn came within an inch or two of tearing my hamstring and causing all manner of knock-on effects down my entire leg that I'm still doing a buttload of stretches for to get my hamstring from the size of a tennis ball as it was in mid-to-late December to where it is now where I'm only really limping on days where it's cold and damp...like today. ****.
However, before anyone goes apoplectic and starts reaching for a handful of P45s for our medical team, it's worth pointing out that Raheem Sterling also has APT, which again if you see him running he looks exactly like the right-hand diagram, so it's a condition that can certainly be managed with physios and massage therapists - but it's also worth pointing out that his season was screwed up by a groin strain that was exacerbated by him being called up for the France squad who assumed it wasn't so bad, and if he does have ATP that would certainly explain his fitness issues since then as his hamstrings were put under additional stress when he was compensating, sort of like how my calf was in a permanent state of cramp as it was having to do all the lifting (literally) for my leg
Or it's bollocks and Danny Rose was sneaking his Mars bars into Tanguy's food for months
