Spurs have made a host of new signings this summer and sold Luka Modric and Rafael van der Vaart. Villas-Boas was delighted Dembele got off to the perfect start, but admits he has no idea how long it will take for his new team to gel.
“You can never predict that,” said Villas-Boas, set to make a new move for Porto’s Joao Moutinho in January.
“You just have to wait for players to play to their full potential and then things start to fall into place. Mousa was extremely good.”
