Bayern Munich winger Franck Ribery scored a sensational volley to lead the German champions to a 1-0 win over Eintracht Frankfurt on Saturday that sent them eight points clear at the top of the Bundesliga with six matches left. Frenchman Ribery, who has missed most of the season due to injury, took off at the edge of the box and sent his mid-air volley past Lukas Hradecky in the 20th minute after the keeper had initially saved a shot from Mario Goetze.
