Spurs did not disclose the transfer fee, which British daily The Guardian put at 30 million euros ($A49 million)

The 22-year-old attacking midfielder, who has made nine appearances for his country, was part of three Eredivisie title-winning squads at PSV and scored 31 goals in 149 appearances.

Bergwijn reinforces Spurs boss Jose Mourinho's forward options with England striker Harry Kane out with a long-term hamstring injury.

"It's an amazing move for me, an amazing club," Bergwijn told the Tottenham website.

"Just look around the training ground, it's amazing. I just spoke to the manager as well. When I was a young boy I looked up to a coach like Jose Mourinho, now I play for him."

Bergwijn is Tottenham's third signing of the January window, with Portuguese Gedson Fernandes joining on loan from Benfica and fellow midfielder Giovani Lo Celso of Argentina finalising a permanent move from Real Betis after an impressive loan spell.

Meanwhile, Christian Eriksen said he wanted to "try something new" after writing an emotional letter to Tottenham's fans.

Eriksen ended his six-and-a-half-year spell with the north London club on Tuesday after he completed a STG 17million ($A33 million) move to Inter Milan.

"I have so many unbelievable memories over the last 6.5 years I was at Spurs," the Danish midfielder said.

"I enjoyed being at the training ground every day and playing games in the stadium so much, but sometimes you just want to try something new.

"So, Spurs fans it has been a pleasure to play at your club and hopefully we meet again in the future."
