Thomas Tuchel called out Dayot Upamecano for giving away the penalty that saw Lazio claim their first-leg round of 16 win against Bayern Munich on Wednesday night.
The Bundesliga champions were looking to bounce back quickly from their difficult weekend tie against league leaders Bayer Leverkusen, but found themselves unable to push past their hosts in Rome.
After failing to convert a number of strong first-half chances courtesy of Harry Kane and Jamal Musiala, Bayern Munich's fortunes went from bad to worse after the break.
