Middlesbrough have made their first signing after promotion to the 2016/17 Premier League with the transfer of Viktor Fischer from Ajax.
The 21-year-old forward, who has eight caps for Denmark, will join for an undisclosed fee and on a three-year deal when the international transfer window re-opens on 9 June.
The winger made more than 100 appearances for Ajax since joining in 2012, scoring 11 goals in 39 matches in 2015/16.
Before Ajax, he came through Lyseng IF’s youth team before moving to fellow Danish clubs Viby IF, AGF and FC Midtjylland.
