Top five talking points: Stoke City 1-0 Chelsea
1. Has Diego Costa landed himself in more disciplinary problems?
This is Costa’s second season at Chelsea and he has already been retrospectively banned twice by the FA.
First it was for a stamp on Liverpool’s Emre Can last season, then after raking Laurent Koscielny’s face with his hands earlier this season.
This defeat ended with a steward making a complaint of assault against Costa for allegedly treading on his toe when he went to collect the ball. The television pictures looked innocuous and on this occasion Costa probably deserves the benefit of the doubt.
2. Was Loic Remy too honest?
Mark Hughes was understandably full of praise after the game for Remy, who tried his utmost to avoid contact with Jack Butland before attempting to score. The French forward failed to regain his balance and direct his shot goalwards.
The game could have had a different outcome had Remy simply allowed contact from the oncoming goalkeeper. as most strikers do.
Chelsea would have won a penalty, with Butland getting sent-off.
3. “That’s why you are going down”
The Potters fans chanted “that’s why you are going down” when they realised they were going to deepen Chelsea’s misery. The champions may only be two points above the drop-zone, but they should start moving up in the table once they get past this rough patch.
They have enough quality to still mount a successful top-four challenge, but Mourinho’s charges remain stuck in trouble partly because of their rotten luck.
Marko Arnautovic scored one of the best goals this season, but Jonathan Walters was fractionally offside in the build-up to the goal. At the other end, Pedro managed to beat the in-form Butland but his shot cannoned off the post. These key moments went for the Blues last season, but now it is a different story.
4. Will Xherdan Shaqiri kick on from this performance?
Shaqiri brought so much excitement to Stoke City fans after he signed from Inter Millan in the summer, but had an underwhelming start to the season. He was clearly the best attacking player in this game as he repeatedly skipped past a hapless Baba Rahman with dazzling skills.
Shaqiri also had an end product to his wing-play, with accurate crosses into the box. Will this be the beginning of an exciting run for the ex-Bayern Munich winger, because the Premier League is richer when flair players like him are at their best?
5. The champions continue to make unwanted records
This defeat means Mourinho has lost seven games in the same season for the first time in his illustrious career. The worrying part is that the Blues have lost 10 games this season and the season is not even at its halfway point yet.
This result also means Chelsea have lost three games in a row for the first time in Roman Abramovich’s era.
