Ajax attacker Lucas Andersen has signed a new contract with the Dutch club.

The 20-year-old's previous deal at the Amsterdam ArenA was due to expire in the summer of 2016.

However, the Dane has now extended his stay with Frank de Boer's side by a further two years.

"At Ajax I can achieve a lot. It is nice that many key players have renewed their contract. My aim is to be one of them. With this group, we can still achieve great things," he told the club's official website.

Director of football Marc Overmars added: "We have a lot of confidence in him. Lucas is a huge talent and now has become a mature player."

Andersen joined Ajax from his boyhood team AaB in 2012.
