Tottenham manager Mauricio Pochettino believes Vincent Janssen will take great confidence from scoring his first goal for the club in their 5-0 victory over Gillingham.

Janssen opened his account from the penalty spot at White Hart Lane after Christian Eriksen's double had earlier put Spurs in control.

Josh Onomah added a fourth with his first senior goal and Erik Lamela completed the rout as Pochettino's side booked an EFL Cup fourth round clash with Liverpool.

Harry Kane's ankle injury means Janssen is set for an extended run in the first team and the 22-year-old showed courage to take the second-half spot-kick, before sliding it into the corner.

"Now that Harry Kane's injured he is our main striker and it's important for his confidence for the next few games," Pochettino said.

"Always I allow them to take the ball and whoever feels more confidence to shoot, but I remember in the national team against England he took the ball and took the penalty.

"I think that it was important for him, to feel the love from the supporters.

"For a striker, always the difficult thing is to create chances but he has a lot of chances to score today. He was unlucky.

"The important thing is that he got into the box and he created a lot of chances and for the future it's important that he feels confidence and for the team it will help a lot for us."

Pochettino handed four players - Cameron Carter-Vickers, Georges-Kevin Nkoudou, Anton Walkes and Marcus Edwards - their debuts, while midfielder Harry Winks was also making his first start for the senior team.

Nkoudou was an £11million summer signing from Marseille but the others are all products of Spurs' academy and none were over-awed by the occasion.

"They play very well, they play with a lot of confidence," Pochettino said.

"I am very happy because if you see the confidence of Carter-Vickers, Harry Winks, Anton Walkes, they were fantastic.

"They come through the academy but they have the quality to impress us and play for the first team.

"It's important for Tottenham and it was fantastic to give the opportunity to play and fantastic experience for them."

Gillingham kept their opponents at bay for 31 minutes but the League One side were outclassed and the pressure told in the second half.

It made for an unhappy night for Gills boss Justin Edinburgh, who spent 10 years at Tottenham between 1990 and 2000 and was left disappointed by his return.

"I had a fantastic time here and I am disappointed because it was not the score I visualised, but the gulf in class came through in the end," Edinburgh said.

"We thought at 1-0 we might have a chance of staying in it but they put on the burners, got to 3-0 and it was damage limitation from then on."
