Guus Hiddink's unbeaten Premier League run came to an end in Chelsea's 1-0 defeat at Swansea City.
Chelsea suffered its first Premier League defeat since the appointment of Guus Hiddink as the Blues lost 1-0 at Swansea City on Saturday.
Hiddink replaced Jose Mourinho on an interim basis in December and has successfully guided Chelsea into the top half following a disastrous start to its title defense.
However, in the first match since Antonio Conte was confirmed as Mourinho's permanent successor, it was the Welsh club which celebrated reaching the fabled 40-point mark at the Liberty Stadium.
