Spurs capitalised on an error from Hornets goalkeeper Orestis Karnezis as Christian Eriksen set up Alli and the England midfielder scored from 12 yards out. Kane doubled Spurs’ lead early in the second half from Kieran Trippier’s pull-back and Jan Vertonghen later headed against the post.
The game was played in a subdued atmosphere, with plenty of empty seats dotted around the ground, and Spurs were often there for the taking. There was a slight air of edginess about their play and Pochettino frowned at his team’s tentativeness in the final third, especially when Kane spurned a decent shooting opportunity with an awkward piece of control in the 12th minute. Watford sensed an opportunity to exploit that unease, showing inventiveness on the break, and Spurs’ defenders were relieved to see Hugo Lloris deny Andre Gray in the 25th minute.
