Troy Parrott made his senior debut for Spurs on Tuesday night as the Premier League side crashed out of the League Cup to Colchester.
The 17-year-old Dubliner played 67 minutes before he was replaced by Christian Eriksen. The game finished goalless in 90 minutes before being immediately decided on penalties.
Just as he did a week ago, Spurs manager Mauricio Pochettino called for a relaxed approach regarding Parrott's future.
"He needs time, he is so young," Pochettino is quoted as saying in the post-match press conference by Football.London.
"For sure he is going to be a very important player for Tottenham in the future but maybe it needs one or two years of being involved and playing in this type of game, like Japhet, like Oliver Skipp.
"Young players need the space in the squad like it was five years ago with Eric Dier, Ryan Mason, Harry Kane.
"We need to create this belief and space again for the younger players to find their natural space in the squad. We are still trying to fix this.
"We need time with the young players, we need time with the new signings like Ryan Sessegnon, like Tanguy Ndombele, it will make us stronger."
