Tottenham assistant manager Kevin Bond praised Andros Townsend after the teenager notched on his debut against Charlton.
The 19-year-old winger put Spurs ahead in the 49th minute of the FA Cup clash at White Hart Lane, scoring with a 20-yard effort.
Former Charlton striker Jermain Defoe then notched a quick-fire brace to make sure of the win.
Afterwards Bond admitted the youngster, who is naturally left-footed, looks to have a bright future at the club.
"I thought it was a terrific performance from someone making his debut," said Bond.
"If Harry (Redknapp) feels he can bring someone in (during the transfer window) to improve the squad then he said he would look at it.
"(But) looking at Andros, it looks like we might benefit from having him around."
Following a disappointing goalless first half, Spurs soon sparked into life after the break thanks to the introduction of midfielder Luka Modric.
Bond believed the Croatian gave Spurs a creative outlet they badly missed in the first period.
He said: "Maybe we were predictable in the first half and you need someone with that something different to unlock the door. He certainly has that."
Defoe returned to the starting line-up after a three-match ban for a red card for an elbow on James Collins during Spurs' 2-1 win at Aston Villa on Boxing Day.
Bond believed the England striker was determined to prove a point by contributing to the win, which earned Tottenham an away tie against Fulham in the fourth round.
"I'm sure Jermain was frustrated because it was a harsh red card," Bond said.
"He was frustrated because he wasn't long back from injury and to sit out another three games meant he was keen to get out on the pitch.
"Strikers live off goals and it's important for them, they become a different animal completely when they find the net."
Charlton caretaker boss Keith Peacock was happy with his team's efforts but admitted substitute Modric made a big difference on the outcome of the game.
"I'm proud of the way the players performed," Peacock said.
"As soon as I saw who was coming on the pitch at half time, I thought we would have a problem.
"You love watching him on the ball, but not when you are playing against him.
"The little pieces I've seen of him, and what I saw in this game, he is right up there with the best."
