Farke said: "Sometimes you get the feeling he tries too much. It's quite normal that players have a difficult spell. I would say each and every player has two, three or four games of a weaker spell during a season of 46 games so I wouldn't interpret too much into it. What he still offers is more or less relentless workrate.
"At the moment he's finding it a little bit difficult. The natural easiness is a little bit away from what it was in the games before but it's always the same, don't interpret it too much into it, just keep going, concentrate on the basic stuff, work for the team.
"There was a feeling that he's sometimes concentrating a bit too much on always having the perfect choice and the perfect complicated pass because he wants to make things happen. "So the message is ease up, keep it simple and make sure we keep the ball. Don't always play the most complicated pass. The end products, goals and assists will come back."
