AVB upset with Spurs defending
Tottenham boss Andre Villas-Boas felt they blew their chances in defeat to Everton.
Villas-Boas, whose side have only kept one Premier League clean sheet away from home, was left to bemoan more late defensive frailties.
Spurs have developed a poor record for conceding late goals - 10 in the last 15 minutes - and that cost them again.
"It was a disappointing result bearing in mind we were leading taking the game into the last minute," he said.
"It has been quite an adventure in the Premier League this season; if we count the number of results that have been going for us before the last minutes we would be first.
"There are so many different reasons. It is not really easy to explain because a couple of them come from different situations.
"It is something we are aware of, which is why we speak about it openly, and it is something we have to improve, seeing off games.
"It is not a mental thing, it is the nature of the game because it was our best period for quite some time in the second half.
"You kind of knew as soon as the kick-off went for the 1-1 they (Everton) would go and have a go and they certainly did.
"It is a difficult blow to take."
