Sunderland boss Dick Advocaat is closing in on his first transfer breakthrough but how do Carl Jenkinson and Sam Byram compare?
The pair - both right-backs - have both been strongly linked with a move to the Stadium of Light this summer.
Jenkinson could be set for a loan move, with Sunderland agreeing a loan fee with his parent club Arsenal despite interest from West Ham United, where he spent last season, and Southampton.
But the Black Cats are also keeping tabs on highly-rated versatile Leeds United defender Sam Byram, who can also play right wing.
A number of Premier League clubs have been tracking his progress at Elland Road.
