Tottenham defender Toby Alderweireld has told NBC Sports in America that he has a strong relationship with fellow centre back Jan Vertonghen.
Alderweireld, 26, was one of Spurs' biggest summer signings having arrived from Atletico Madrid, which followed an outstanding loan spell with Southampton.
The move to White Hart Lane not only gave Tottenham a centre back they can rely on, but also handed Alderweireld a reunion with Vertonghen.
The two centre backs both came up through the ranks with the now-defunct Belgian side Germinal Beerschot, and then moved on to Ajax together, where they struck up a strong partnership, whilst they also feature regularly for the Belgian national team.
It therefore made perfect sense for Mauricio Pochettino to put Alderweireld and Vertonghen back together in the heart of his Spurs defence, and so far, it's a decision that has certainly paid dividends for the Tottenham boss.
With just eight goals conceded, Spurs have the joint-best defensive record in the Premier League, and much of that is down to the displays of Alderweireld and Vertonghen.
Now, speaking to NBC Sports in America, Alderweireld has highlighted the partnership with his fellow Belgian, and even revealed that the duo analyse certain strikers and how to deal with them before each Tottenham game, giving them greater understanding of their opponents - a key factor in Spurs' impressive defensive displays.
"I know him, especially from Ajax because I played with him but growing up in Belgium I didn’t play with him because he is two years older than me," said Alderweireld. "It is nice to play with him, we know each other well and I think you can see that on the field."
"We talk a lot before the game about how to defend and how we have to do this. 'This kind of striker we have to do this’, so we talk a lot before the game and in the game it is split second. If you have to tell each other every time ‘watch this…’ then the moment it is gone. We know what to do in certain situations. It is very important."
"We know from each other that when he makes a mistake I cover and when I make I mistake he picks it up. That is important not only with me and Jan but the team wants to work very hard and make sure other players’ mistakes don’t hurt us. That is why we have a good solidity," he added.
