10. Henrik Dalsgaard - Brentford - Loan
Oh, this is a lovely deal. The Bees have forsaken the Danish right-back since securing promotion, and he's up for grabs. His work rate is terrific, and he'll definitely add something to the side. (Photo by Alex Davidson/Getty Images) Photo: Alex Davidson
11. Mark Travers - Bournemouth - Loan
A lengthy spell on the sidelines sees Sunderland snap up another goalkeeper, but on a short-term deal this time. He's not had much of a shot with the Cherries, and will be hungry to prove himself. (Photo by Nathan Stirk/Getty Images) Photo: Nathan Stirk
12. Peter Gwargis - Brighton - Loan
Brighton's loan army is up there with Chelsea's in terms of scale these days, and the Black Cats pluck a prospect from them here. He's a pacey attacking midfielder. (Photo by Dan Istitene/Getty Images) Photo: Dan Istitene
