Andre Villas-Boas and the players have trained at the fantastic new facility in Enfield for the first time this week.
It's safe to say that William, who has captained the team this season and is a multi-title winner with 84 caps for France to his name, has been blown away by Hotspur Way.
"It’s one of the best, maybe in the world," he said. "Everything is perfect here to play football, and to feel good.
"The club has built a training facility for the players and when you come here you don’t want to leave! You don’t want to go back home!
"The pitches are unbelievable - if you make one mistake, you can’t complain about the pitch! The pitches are great, the groundsmen do everything for us so every time we come here in the morning, the pitches are perfect.
"What we need now is to win some trophies because with this facility, we can do something."
