Frank Lampard has lamented the "clear" defensive mistakes that his Everton side made as they were humbled 5-0 away to Tottenham Hotspur.
An own goal from Michael Keane began the rout in north London 14 minutes in, before Heung-Min Son added a second only three minutes later.
Before the break Harry Kane bagged a third for his side - before Sergio Reguillon added a fourth just after the interval with the England international striker later completing his brace in the 55th minute.
