"Twenty-four players all trying to get a start in every single game; I think it's a very good thing for us", Pochettino said. "We were professional and the job is done".
"Soccer was always the one for me, as much as I love hurling, and I wouldn't change anything". "For us, it is an opportunity to come back closer to the Champions League places, which is a priority".
"I think today is the FA Cup. He is going to recover his real level and improve because he is more mature and in a tough moment you learn a lot".
Lamela's display contrasted to that of Fernando Llorente, who missed two clear-cut chances in the second half to extend Spurs' lead.
Erik Lamela extended the home team's lead in the 34th minute, gently caressing the ball past Newport's Day. This time, Son wriggled forward and spotted Lamela. The Argentinian cushioned the pass with a nice first touch, and slid the ball past the keeper with his trusty left foot.
Then it was all Spurs as the confidence drained from the Welsh side and the quality began to tell.
Day was called into action twice in quick succession on 31 minutes as he parried away Eric Lamela's strike from 19 yards out and blocked Son's effort from a tight angle on the right at his near post seconds later.
With Harry Kane, Eriksen and Dele Alli all on the bench it was down to Son and Lamela to provide the creative spark for Spurs.
Newport took the game to a sloppy-looking Spurs in the early stages, with the hosts seemingly not having learned their lesson from the 1-1 draw in the reverse fixture.
Despite the Welsh side being so close to claiming a massive scalp in Premier League side Tottenham, with the draw came a dream trip to Wembley - potentially the only chance Newport have to visiting the home of English football this season, having been knocked out of the Checkatrade Trophy and now placing 11th in League Two.
