The most important quality Tottenham have helping their Premier League surge

The north London side are fourth in the Premier League - and not for no reason.

For most Premier League sides, losing a winger and then a senior centre-back would be a huge blow.

For Tottenham Hotspur, it still is a blow. But it's nowhere near disastrous.

Indeed, Tottenham's success this season - they are still in the FA Cup, importantly, while they sit fourth in the Premier League, only five points behind leaders Leicester City - is down to many factors. Arguably the biggest, though, is their newfound strength in depth.

It is such an important factor for Mauricio Pochettino's men this term and it's something they couldn't fall back on last campaign.

Now that Jan Vertonghen is out injured, Spurs have the promising Kevin Wimmer to step in and fill the void. Last season, Federico Fazio was the best bet and even Vlad Chiriches ended up at centre-back.

The sale of Andros Townsend, meanwhile, has had no bearing on the first team. Last term, it would have at least made a big dent on Tottenham's bench.

This time around, there is just too much quality. Christian Eriksen, Heung-Min Son, Erik Lamela, Nacer Chadli, Mousa Dembele and more.

Tottenham's Premier League surge is not just down to their best XI - it's their whole squad. They boast an impressive level of squad depth, one many top-flight rivals should simply envy.
