There could be big changes in the defensive department if Tottenham succeed with their reported interest in the Belgian.
Recent news has come out from the Times that Toby Alderweireld has notified friends that he is very close to joining Tottenham Hotspur and their Belgian contingent, and this is likely to have drastic implications for more than a couple of Tottenham defenders.
While that story in itself remains unproven, with contrasting reports from the Mirror indicating that the Belgium international's club last season, Southampton, are in poe position, if true it implies that Tottenham are set to make big changes in the heart of their defence next season. Jan Vertonghen is the first choice centre back for Mauricio Pochettino, having featured in 32 of the Premier League's 38 matches last season, while summer signing Kevin Wimmer has to be considered at least one of the four first choice central defenders following his arrival.
Aside from Veronghen, Eric Dier started more games in defence than any other Spurs centre back last season, even if he did play some of his games at right back, and the 21-year-old has definitely shown enough to suggest he is an England international in the making. So that's another one of the four spots taken.
But what about the players that would be most at risk from a Alderweireld arrival, those already scrapping for that final spot?
Vlad Chiriches and Younes Kaboul have long been thought of as disposable at Spurs. The Frenchman captained Tottenham for their first eleven league games, but hasn't featured since the home loss to Stoke in Novemeber. It isn't much of a stretch to imagine that a falling out between the 29-year-old and Pochettino would have contributed to such a fall from grace.
Romanian Chiriches has at times this season been so bad in central defence that it has almost been funny. He looked much more comfortable at fullback, but considering that isn't his best position, he too would benefit from switching clubs.
But the individual that would be a surprising candidate to be moved on would be Federico Fazio, the flagship Argentinian central defensive signing last summer that was supposed to herald Pochettino's arrival.
He too has looked poor at times for Tottenham, unable to function in such a high line, but in other matches he has been a predictable giant of a defender, powerful and imposing in the air. Nevertheless, for much of last season, Dier was preferred to the 28-year-old.
The former Sevilla defender is the man whose first team role will be most at risk from the possible arrival of Alderweireld, as it appears he hasn't convinced anyone since his move last year, and he could be joining Kaboul and Chiriches on the 'available list' this summer.
