Tottenham have agreed to let teenage centre half Luka Vuskovic join Hamburg on loan for the season.
The German giants, back in the Bundesliga after promotion last season, have been waiting for a green light on the deal from London.
Spurs want Vuskovic to play regularly to maintain his rapid development, they do not want him to spend a season on the fringes but have been wary of cover for first choice pairing Cristian Romero and Micky van de Ven.
Kevin Danso is next in line and started in the Super Cup final against Paris Saint-Germain when head coach Thomas Frank started with three central defenders, and Radu Dragusin is in the final stages of his rehabilitation from the cruciate knee ligament injury he suffered in January.
