Man in the middle: Roger East
Roger East will be the man in the middle when Swansea City host Aston Villa on Boxing Day (3pm).
The experienced Wiltshire official will be taking charge of a Swansea game for the 18th time, and for the 12th time at the Liberty.
He has officiated Swansea games in League One, the Championship and the Premier League.
He previously helmed this fixture on Boxing Day during the 2014-15 season, when Swansea claimed a 1-0 win thanks to a Gylfi Sigurdsson free-kick in sodden conditions.
East will be assisted by Matthew Wilkes and Derek Eaton, while Brett Huxtable is the fourth official.
