Gosh, golly, I can't say enough good things about the man for whom this thread is named. He's been nothing but an absolute pleasure to watch in a Spurs shirt.
So, if I'm reading all the contract bumpf correctly, Toby can basically walk out of Spurs after 2020 for free or Spurs can sell him between now and the commencement of his extension in June, 2019, about 16 months from now for somewhere in the fair market range of about 30 million quid.
If we were looking at a younger player, now would be the critical moment to sign him to a lucrative longer term deal. But we're talking about a player - as fine as he has been - prone to some bad ass muscular/soft tissue injuries who will be 29 if we sell him or 30 when he walks for free.
I'm not throwing good money after bad bones. If we can keep him, that would be great. He'll never have a defence partner as totally in sync with him as Jan Vertonghen. And he'll never look as effective for breaking that partnership. I bet he knows that.
But if this player - or this player's agent - thinks he can put the club over a barrel in these contract talks, he's sadly mistaken. Spurs hold all the cards over the next 28 months. Toby will never net a huge deal if Spurs force him to honour that contract and force him to stay until he's 30. No one will throw huge coin at an injury prone defender over 30.
By all means, work hard and fair to give him a good offer and keep this great central defence partnership going. No other club will stand to gain as much from a healthy, motivated and happy Alderweireld.
