Barça's record-breaking treble win under Luis Enrique is statistically the best in football history

Luis Enrique's Barcelona side has not only made history due to their treble of La Liga, the Copa del Rey and the Champions League in 2014/2015, but also because they boast the best statistics in eight instances. This has been deduced from a comparative table posted on Twitter by @Barca19stats.

Since Jock Stein's Celtic side became the first club to impose themselves across two domestic competitions and the European Cup in 1966/1967, only seven clubs have achieved the same level of success. Barcelona have the honour of being the only side to do the same on two occasions, in 2008/2009 under Pep Guardiola and now with Luis Enrique.

According to the statistics, Barça's current side won the most games out of all of the treble winners (50 times over Celtic's 47). Also, they have scored the most (175 times, one more than Celtic), as well as boasting the best goal difference (+137) and the most number of clean sheets (33).

Ajax also dominate four of the criteria. They have the best win percentage (88%) after being defeated only one in 48 games. They also had the best defensive record (28 goals against), conceding the least in terms of goals per game (0.58). 

Celtic have the best goals scored per game ratio (2.95) and Manchester United played the most games to achieve their treble (63).

Here are the eight teams who have achieved the treble and more about their year of success
