Arjen Robben's last-minute winner sealed Bayern's 2-1 comeback victory at Mainz as Friday's battling display further extended Bayern's huge 11-point lead.
The Mainz result saw Bayern claim a new record for the least goals conceded in the first-half of the season as their defence have leaked just four goals. Bayern have equalled their own record for the highest goal difference at the halfway point of plus 37.
