Tough one to call this one, with Brentford on a good run with 1 defeat in 12 matches.
Swans have a bit of an injury crisis with several players injured, plus the fire sale of three players in the January transfer window make it hard for Graham Potter to put a competitive side together.
They do have home advantage though, and with the match having been moved to a Sunday 4pm kick off due to live tv coverage, the extra day will help the players recovery time from a tough match at Leeds last Wednesday.
