Swansea are short of midfield numbers as Jonjo Shelvey completes a four-match suspension and Ki Sung-yueng is away on international duty, but Gylfi Sigurdsson (foot) should play and winger Jefferson Montero could make the bench after making a quicker than expected recovery from the hamstring injury he suffered on Boxing Day.

Full-back Cesar Azpilicueta remains sidelined with a groin complaint but is set to return to training next week.
