Spurs spent £12M to sign the youngster before sending him on loan for two seasons in the Polish and Belgian leagues where he impressed enough that reports are suggesting that Frank is considering integrating him into the first team ahead of the new season.
The Croatian became an established first-team regular at Westerlo last season and even scored seven goals from central defence including an overhead kick against Bruges that won the Pro League’s Goal of the Season prize.
The Daily Mail report that There is lots of interest from Germany for the youngster to go out on loan once more but there is a worry that if he is not introduced into English football now, he may never be.
Tottenham fans got their first glimpse of the centre back in the recent pre-season friendly against Reading, and they could be about to see a lot more of him as the season goes on if he does remain with the North London side who are keen to keep him.
However, the 18-year-old faces a monumental challenge in getting game time at Spurs due to their quality in defense. This means even if he stays he will not get the game time necessary to perform at his best which means a loan move may suit him better in what is a tricky situation.
