Europe's deadliest attack: Barca trident

Barcelona set a new record for goals in a calendar year by a Spanish team after hammering Real Betis on Wednesday night - and they have also finished 2015 as the most prolific outfit across Europe's top five leagues.

The Catalan club, led by their ferocious 'MSN' attack (Lionel Messi, Neymar and Luis Suarez), notched an incredible 109 goals in La Liga across the last year, giving them a goals per game rate of 2.86 (a figure no side in England, Spain, Italy, Germany or France can match).

PSG were a not-so-close second, still 0.16 goals per game behind Barca, while Manchester City were the highest-placed Premier League side, with their 2.07 ratio out-stripping that of current table-toppers Arsenal (1.84).

Unsurprisingly, Barcelona also top the charts for goal difference per game in 2015, with Bayern Munich this time taking up second spot, while Borussia Dortmund sneak into the top five after a stunning year under first Jurgen Klopp and then Thomas Tuchel.
