Ange Postecoglou spoke to ITV after Tottenham's victory against Tamworth: "It was a challenging game as we expected it to be.
"They made it hard for us, with the surface it was about us staying calm and being persistent in our football.
"In the end, we got the job done."
On the message going into extra time: "Stay calm and persistent. We knew we would finish strong and you could see they were tiring a bit.
"It's a game of football you go into it with trepidation and knowing you can slip up with the challenges.
"Most parts the boys kept their heads. I thought they stayed clam and persisted and got through.
"We are through to the next round and that was the objective for today.
"Tamworth did really well and should be proud of their efforts. For us, we move on."
