Winger Sinclair has been a revelation at the Liberty Stadium since joining from Chelsea last summer, scoring 17 league goals to lead City`s promotion charge - with no other Swans player even in double figures.
While Sinclair has been a menace in attack, Wales international Williams has been proving his worth at the heart of defence.
The 26-year-old, who joined Swans from Stockport in 2008, is the only outfield player in Brendan Rodgers` squad to have started all 42 league games to date this season, scoring three goals along the way.
