FC Barcelona v Real Sociedad de Futbol - La Liga
Suarez became a part of the deadly MSN trio that terrorised Europe for 3 years

Barca had begun to experience a decline of sorts since the departure of Pep Guardiola to Bayern, but Luis Enrique took over as manager in 2014, and the former Catalan legend led his club to an incredibly successful treble-winning campaign.

Most fans, however, remember it as the season in which one of the deadliest attacking trios in football history was first formed. Luis Suarez joined from Liverpool in July, with Enrique taking a big leap of faith in the Uruguayan hitman, given that his ban following the infamous biting incident in the World Cup prevented him from playing for four months.

Suarez's first match was a 3-1 loss in the El Clasico, but he kicked off his career at Catalunya after scoring against APOEL in the Champions League. Incredibly, he ended the season with 25 goals and 20 assists, and MSN ended up scoring 122 goals, making them the most lethal trio in Spanish football history.

The signings of that summer played a huge role in their extraordinary success. Goalkeepers ter Stegen and Bravo arrived to replace the departing legend, Victor Valdes. Carlos Puyol retired, and Cesc Fabregas moved to Chelsea, meaning that the Blaugrana had some big holes to fill in their squad.

Ivan Rakitic arrived from Sevilla having won the Europa League the previous season and formed a formidable midfield trio alongside Iniesta and Busquets. Thomas Vermaelen and Jeremy Mathieu were brought in to fill the void left by Puyol, but neither of them was quite up to the mark. Thankfully, Mascherano and Pique stepped up to fill in the centre-back slots.

Bravo, ter Stegen, Vermaelen and Mathieu might not be their most eye-catching signings of late, but Barca's summer dealings of 2014 deserve a place on this list simply because of the enormous impact that Suarez has had in recent years. He's already scored 87 league goals in 101 appearances, which is an almost unreal goals-per-game ratio. He might already be 30 years old, but is definitely one of their best goalscorers of the past decade.
