Tottenham Hotspur midfielder Dele Alli has said manager Mauricio Pochettino was crucial to his decision to sign a new six-year contract and he believes he is in "a great place" to improve.
Alli, who was already under contract until 2021, signed a new deal on Tuesday that commits him to Spurs until 2024.
"He is a massive part of wanting to be at this club," Alli said after setting up two goals in Wednesday's 3-1 Carabao Cup victory at West Ham.
"The fans are amazing, the chairman, everyone -- the whole club's amazing. But as players you work with the gaffer, you want to have a good relationship with the manager, and we all feel like we've got that here.
"We all love the way we work, the style of play. We all want to be a part of it. He's done a lot for me so far and hopefully he can keep helping me to improve.
"I'm delighted. It's a great gesture from the club, with a few years still left on my contract, to renew it. I want to keep working as hard as I always have done and keep improving."
Harry Kane and Davinson Sanchez agreed new six-year contracts in the summer, while Pochettino, Son Heung-Min, Harry Winks and Erik Lamela have also signed long-term deals.
Alli said he saw a bright future despite delays surrounding Spurs' move to a new stadium, with the players determined to "achieve something great."
"We want trophies, not only for us but for the fans as well, and it will be that bit more special winning it here together with the amount of work we've done," he said.
"People can have their opinions with what's happening with the stadium and stuff, but as players, as a club, we all need to stick together.
"When we move into the stadium, after a few games or maybe after a lot of games, this will all be forgotten with the switch-over. Hopefully the fans will love it. We're all looking forward to it, we're all excited.
"This is our best [Premier League] start in history, even though it might not feel like that because we haven't hit the form we know we can. I think that says a lot about us, that we've had the start we've had and still know we can play a lot better."
Alli said the move to a new home had played "a little part, not a massive part" in his decision to sign a new deal.
"The stadium and the training ground are great, but you can have all that and still not improve as a player," he added.
"As a young professional, I have to think about what's best for my career and where I can improve. I think I'm at a great place to do that."
