Chelsea suffered an injury blow as Thiago Silva limped off the pitch in the first half against Tottenham.
The Brazilian defender stretched to clear a ball in his own half and immediately seemed in pain as play initially carried on.
Silva remained lying on the ground though and was replaced by Andreas Christensen, who had previously featured in just five Premier League matches so far this season.
When he went off, Silva had completed more passes than anyone else on the pitch and was marshalling a Chelsea defence which had very little to do in the first half.
