Versatility
Following the loss of loanees Modou Barrow and Alfonso Pedraza, Leeds have been left with Souleymane Doukara and Stuart Dallas as options on the left flank.
However, neither hit the heights that was required of them last season and were both replaced following the six-month loan signing of Pedraza in January.
Bryan can offer top-class quality from left-back as well as the left of an attack, giving Christiansen more options if Doukara and Dallas once again struggle to provide any consistency from the flank.
