"I am delighted to be here," he told Spurs TV. "Over the last years Spurs have become a very big club in England.
"They finished in the top four a few times and for me it was one of the best clubs in the Premier League and that is one of the reasons I wanted to come here.
"There is a lot of quality and I think everybody wants to make a good season.
"Last year in the first six or seven months, they were up there for the title, the championship.
"After that it was not that well, but this year I think we will compete a few more months longer."
The 25-year-old is just pleased to finally be a Spurs player.
"I wish the Premier League started tomorrow," he said.
"I have to wait a bit longer but I am looking forward to starting and playing for Spurs.
"I am very excited. It has been my favourite competition for so many years.
"All the Belgian players I play with in the national team are very positive about it and I am looking forward to playing against them too."
