Everton's English striker Dominic Calvert-Lewin (centre) celebrates with teammates after scoring their first goal during their English Premier League match against Tottenham Hotspur at Tottenham Hotspur Stadium in London, on September 13, 2020.
The opener arrived 10 minutes after the break as Calvert-Lewin rose highest to power Lucas Digne's free-kick into the top corner.
Mourinho said on Friday he hopes to add another striker before the end of the transfer window to add some support to Kane, but any new arrival will need better service to work with as the England captain did not have an opportunity to get his side back on level terms.
