FC Barcelona is known for its tiki-taka style of constant touches between short passes. That style allows them to control the ball for 70 percent of the game and to make the opposing team run themselves ragged — but their defensive strategy of applying constant pressure means they also run themselves pretty ragged:
According to Stats Inc., which tracks the distance each player travels in a match, Barcelona’s players have covered 627,366 meters of turf during their six Champions League knockout-round matches, or about 390 miles. Its opponents, meanwhile, have run 611,120 meters or 380 miles, about 3% less, which is significant considering they are all chasing the same ball.
