Pochettino warned his players to get ready for another thrashing in next month’s Carabao Cup final if they didn't pull up their socks.
"If we want to match them and compete with them in the final then we have to compete in a different way," he said.
"They were more aggressive than us. They were better than us in all areas. Of course, it is going to be different at Wembley. The feeling the players have now is good because they know if they repeat this performance it will be the same result.
“We need to improve and we need to push ourselves a little bit more. We have to learn. If we want to compete with Liverpool, one of the best teams in England for many years, we have to raise our level.”
