Referees add more extra time when the big teams are losing

Football (soccer) enthusiasts suspected it, but now statistics is confirming it. After analyzing all the matches of the Spanish league “La Liga” from the 2014-2015 season, two experts in sports science have found that the greater the difference on the scoreboard, the less stoppage time is added to the end of the game. When the score is tighter, however, referees tend to add more stoppage time when the team in the higher division is losing.
