Dembele revealed the Tottenham manager was unhappy with his teamâ€™s efforts against the Hammers.
"He was very disappointed," Dembele said. "I thought we looked much better in the first half than the second.
"In the second we looked very tired and (there was) not too much passion.
"These kind of games you have to win if you want to have a good season so itâ€™s a shame."
