They are a core element of every team: the players who graft for the team without taking the glory. They’re indispensable for success on the pitch and for Official Fantasy Bundesliga coaches too, as they earn as many points as the top stars do but cost just a fraction of the price. Our three experts have dug deep to reveal their three unsung heroes of the season so far.

And thanks to the unlimited transfers available during the international break Fantasy Upgrade, you can snap them up right away!

The Scout: Genki Haraguchi (Hertha Berlin, 9.3m)

44 points represent an incredible return for a player yet to score this season. Genki Haraguchi has been key to Hertha Berlin’s success with his hard-running and tackling all-action style. The 59 challenges alone he has won so far have earned him 20 points.

The Japan international is a tireless worker and hasn’t missed a second so far. He also has a keen eye for a pass, as his two assists suggest. For me, he is as important to Hertha’s game as top scorer Vedad Ibisevic. I wouldn’t recommend buying Haraguchi before Matchday 8 however, as the winger is on international duty in Australia next Tuesday. As Hertha are playing Borussia Dortmund on Friday, it’s more than likely that Pal Dardai will let him rest. Even though he can hardly do without him.

The Coach: Vincenzo Grifo (SC Freiburg, 11.5m)

With a record of three wins and three losses through six games, SC Freiburg are enjoying a strong start as a newly-promoted side and, based on their recent performances, an immediate return to the second tier is unlikely.

The man leading the charge on the pitch and in the Official Fantasy Bundesliga is Vincenzo Grifo. The joint-highest scoring midfielder on 50 points (the same as Franck Ribery), the 23-year-old set-piece specialist costs just 11.5m. Grifo had a hand in 19 goals in 31 appearances last season and has already chipped in with one goal and two assists in 2016/17. Not to delve too deep into the mind-set of ‘The Expert’ it’s also worth noting that he’s had the third-most shots on goal (behind Robert Lewandowski and Andrej Kramaric) and set-up 20 goalscoring opportunities for his team-mates – a league high.

The Expert: Sebastian Rudy (TSG Hoffenheim, 10.5m)

I brought Sebastian Rudy into my side after TSG 1899 Hoffenheim’s goalless draw with VfL Wolfsburg on Matchday 3. It may have seemed like an odd move at the time, given Die Kraichgauer’s skipper had picked up just four points in the stalemate at the WIRSOL Rhein-Neckar Arena, but not once have I regretted my decision to snap him up.

The third highest-scoring midfielder in the game behind Franck Ribery und Grifo, Rudy has played every minute of Hoffenheim’s season thus far, while his tackle success rate is one of the highest in the game (Rudy has accrued 22 points in that particular category). His three assists in six appearances prove that there is more to Rudy’s game than just winning challenges, however. If he can nick a goal or two every now and then, he could become one of the most sought-after midfielders in Official Fantasy Bundesliga.
