#4 Timo Werner proving to be ineffective
While Timo Werner continues to impress with RB Leipzig in the Bundesliga (despite a dip in form last season), the fact of the matter is that he has been drawing blanks with the German national team.
A trip to Russia in 2017 for the Confederations Cup saw him finish as one of three top scorers (3 goals) but he couldn't replicate that form at the World Cup. In fact, the only goal he has scored in 2018 was in a friendly against mighty Saudi Arabia.
Low had moved him from the role of a central striker (he isn't even a poacher) to a wide forward and that had helped him create space for himself. His performances in that role were much more productive at the World Cup when he moved out wide, even though there was a lack of goals.
His pace is also far more useful when he drifts in from wide positions. But coaches and defenders have figured out his modus operandi and, by denying him space to work with, they have managed to isolate him.
Of course, he still gets into good positions when he has the ball or wins it back. But without a strike partner to form a partnership with, Werner hasn't even been able to come up with an assist.
