Thomas Tuchel could reportedly be planning a staggering tactical switch-up targeted at stymying Bukayo Saka against Arsenal tonight.
Bayern Munich welcome Arsenal to the Allianz Arena in the Champions League quarter-finals after a 2-2 draw in the first leg.
And German newspaper BILD believes they have spotted a potential surprise admission - thanks to the help of the wind.
Heavy gusts of wind at Bayern's Sabener Strasse complex meant that curtains and canopies obscuring the training pitch didn't close fully.
That allowed BILD reporters to spy the team's final match in preparation for their European clash.
