6. Herbie Kane - Liverpool to Portsmouth/Sunderland/Coventry City
Interest in the 20-year-old has been high this summer, and it's still no clear where he's going to end up. League One sides will be scrapping it out on Deadline Day to secure a last minute deal, that's for sure.. (Photo by Alex Pantling/Getty Images) Photo: Alex Pantling
7. Arvin Appiah - Nottingham Forest to Various
Strange one this, as he's tipped for a hefty £8m move to Spain. However, given his potential, Forest are also said to be contemplating loaning the youngster to an EFL side instead.
