LONDON (AP) Defending champion Chelsea and absent manager Jose Mourinho returned to unwanted crisis after the troubled giants lost 1-0 at Stoke in the English Premier League on Saturday.
Chelsea's third straight league defeat - its seventh in 12 matches - placed the preseason favorite 16th in the standings, just three points above the previously unthinkable relegation zone.
Mourinho missed the away game after receiving a stadium ban for his behavior toward match officials in a 2-1 defeat at West Ham in October.

Also, Manchester United ended its Premier League scoring drought with a 2-0 win over West Bromwich Albion, while Leicester striker Jamie Vardy scored for the ninth straight league match in a 2-1 victory against Watford. Newcastle, meanwhile, moved out of the relegation zone following a 1-0 away win against Bournemouth.
After a fiercely fought first half, Mark Hughes' Stoke broke the deadlock when Marko Arnautovic scored with an acrobatic effort in the 53rd minute.

Ultimately, Chelsea failed to build on renewed optimism following the Champions League 2-1 win against Dynamo Kiev midweek, despite Mourinho's name being frequently chanted by loyal Blues fans at Britannia Stadium.

Lukaku's goal was his seventh in his last seven appearances against the Hammers.
