Tottenham have announced the signing of AZ Alkmaar striker Vincent Janssen.

The striker has signed a contract with Spurs until 2020.

A Holland international, the 22-year-old was the top scorer in the Eredivisie last season with 27 goals.

He made his senior debut with Almere City in the second tier of Dutch football, scoring 32 goals in 74 appearances during a two-year spell, before sealing a move to AZ last summer.

In his one season at AZ, his 27 goals in 34 league appearances helped them secure a top-four finish.
