But who has impressed most in the opening 16 games of the 2016/17 campaign and who has racked up the most points in their respective position? bundesliga.com breaks down the numbers of the top five unwavering defensive rocks...

Watch: The Top 5 Official Fantasy Bundesliga players of the season so far:

1) Willi Orban (RB Leipzig, 146 pts)

Orban has not missed a kick in what has been a whirlwind debut season for Bundesliga newcomers Leipzig. Ralph Hasenhüttl's side have made waves with their fearless brand of attacking football, but it is worth nothing that they are equally as tenacious defensively. Their captain has led by example at both ends of the field, amassing 81 of his 146-point haul for duels won, as well as an additional 12 for goals scored.

Köln's Hector is another of this season's defensive ever-presents. The Germany international has collected 48 points for appearances, sometimes in his favoured left-back position and other times in a defensive midfield role. He gets stuck in regardless and even outstrips Orban in the challenges won department (87 points). Both men have been deducted 15 points for goals conceded, however.

3) Bastian Oczipka (Eintracht Frankfurt, 127pts)

Fourth-in-the-table Frankfurt boast the second most watertight defence in the league so far this season, a fact that is reflected in Oczipka's 14-point return for clean sheets. No other player on our top-five list has recorded as many shut-outs as the Eintracht left-back, who has also totalled 117 points for appearances and won duels combined. A further eight have come from wins, goals and assists. He is currently valued at 8.65M.

4) Frederik Sorensen (1. FC Köln, 122pts)

Sorensen is another integral part of a formidable Köln backline. The Dane enjoys an above-average points return for appearances (46) and duels won (75), but comes up short in the final third compared to his aforementioned contemporaries. That being said, he is favourably priced at 11M - less than Orban (11.65M) and the second most expensive defender in the game, Hector (14.9M).

5) Konstantinos Stafylidis (FC Augsburg, 122pts)

If you are after a real bargain, however, look no further than Stafylidis. The Augsburg favourite loves to get forward, has a veritable rocket of a left foot and is a genuine threat from set pieces. Like Orban, the Greek defender has scored twice in the Bundesliga this season, but he comes in at almost half the price (6.9M). What is more, as a left-back, he is always going to contest more than his fair share of duels.
