That wasn’t in the script.
John Terry gave Chelsea the lead with a fairytale goal on what is likely to be his penultimate goal for a club he has spent 22-years with.
However, Terry has given us a stark reminder of why he hasn’t been in Antonio Conte’s thinking this campaign.
The 36-year-old put it on a plate for former Tottenham midfielder Etienne Capoue, who made no mistake, beating Asmir Begovic and drawing Watford level.
Chelsea have work to do.
