Chelsea 2 - 2 Watford
Diego Costa scored twice as Guus Hiddink's second spell as Chelsea boss started with a draw against Watford.
It could have been more for Hiddink, in charge after Jose Mourinho's sacking, had Oscar not missed a late penalty.
Spaniard Costa hooked in the opener for the Blues before Nemanja Matic's handball allowed Troy Deeney to level from the penalty spot.
Odion Ighalo's deflected shot gave the visitors the lead, only for Costa to fire in and earn Chelsea a point.
