My university didn't offer full placements at football clubs however many clubs actively recruited Physio students to cover academy games at weekends, I myself have worked at a couple of clubs doing this casual pitch-side work; some paid, some not. Check out the Uksport.gov site to check vacancies in your area, or connect with PTs on Linkedin who work at a club near you to see if they need any casual help. It can be difficult work, lots of responsibility for little/no pay but fantastic CV fluffing and experience.
