The Spurs chief told ITV4: "We were expecting a tough game - it's an intimidating place to come - but we started well and passed the ball great.
"There was great movement everywhere, I couldn't have asked for more. It was excellent.
"Jake did well and Andros (Townsend) came on and did well. It was good for them to get a chance to play and hopefully we can keep doing that in the competition.
"It's one game and you can't get carried away - it'll be different on Monday night at Old Trafford, that's for sure."
