Matt Law reported that Alderweireld's future in doubt as he was left out of North London Derby and also for first tie against Juventus. Player declared himself fit for derby game but was left out (maybe for fitness concern) He has not signed new contract and has contract till 2019. Spurs can activate 1 year extension in 2019 but when they do that, his release clause would be 25 Million. Matt Law mentioned Spurs might have to sell him if they can't agree new contract with the player, also mentioned players should prove their fitness after long term injuries. http://www.telegraph.co.uk/football...ds-tottenham-future-fresh-doubt-belgian-left/ If they don't agree new contract then hopefully we are in for him. Otherwise they will lose him for just 25 Million next season.
