Luke Ayling will be sidelined for two months after suffering a knee injury against Nottingham Forest, and Leeds must work out a way to combat that.
Regarded as one of the club’s most important players, Marcelo Bielsa must choose the best possible option available to him. Here are five options:
The most obvious choice, Berardi is experienced and right-back is his natural position. The Switzerland international is currently working his way back to full fitness.
A product from Thorp Arch, Shackleton continues to impress when given a chance – most notably from the bench against Swansea City. Good going forward, but question marks in defence.

Liam Cooper and Pontus Jansson continue to excel at the back, but Kalvin Phillips has shown he can play in the same position. Instead of using full-backs, why not switch to a three-man defence?
Free agent right-backs?
There are plenty on the market. Former England international Glen Johnson remains without a club, while ex-Newcastle United star Jesus Gamez is also a free agent.
Dallas and Alioski?
This should be considered last resort by Bielsa. Both left-footed, the duo can operate at full-back. But Alioski is much better going forward and Dallas is becoming a utility option – it remains an option.
