The Blaugrana have had a busy offseason, signing Claudio Bravo and Marc-Andre ter Stegen in goal, Jeremy Mathieu and Thomas Vermalen in defense, Ivan Raiktic in midfield, and the Uruguayan up front.
Their total summer spending is 153 million euros, comfortably more than nearest rival Liverpool.
The Reds got a big 88 million euro payoff from the sale of Suarez and have been ambitious throughout the summer ahead of their return to the Champions League.

Adam Lallana, Dejan Lovren and Rickie Lambert all joined from Southampton, Lazar Markovic was a big-money acquisition from Benfica, and Emre Can arrived from Bayer Leverkusen. The spree added up to 131 million euros, almost 40 million euros more than the club's nearest rival in the Premier League.
Real Madrid is third in the list after spending 120 million euros. The Spanish giants have had something of a quiet summer by their standards, signing just three players: Keylor Navas, Toni Kroos and James Rodriguez — the latter for a whopping 80 million euros.
Hot on their heels is city rival Atletico Madrid. The Liga champions lost key members of their squad this summer but have been ambitious in the market, signing Mario Mandzukic, Antoine Griezmann and more for a combined 101.5 euros.

One of the teams to have raided the Vicente Calderon for new talent was Chelsea, which signed Diego Costa and Filipe Luis from the Spanish capital, along with Cesc Fabregas from Chelsea, to take its summer spending to 93.5 million euros.
Staying in London, Arsenal is sixth after buying the likes of Alexis Sanchez, Calum Chambers, Mathieu Debuchy and David Ospina for just over 77 million euros.
Manchester United suffered disappointment last year but signaled its ambition to return to the Premier League top four by signing Ander Herrera and Luke Shaw for a combined 73.5 million euros.
Manchester City has had its spending curtailed by Financial Fair Play but has still splashed out 65.5 million euros on new players, the majority of it on Eliaquim Mangala from Porto.
Southampton has seen many players leave this summer, but the club has been active itself by signing Dusan Tadic, Shane Long and Graziano Pelle and more for a total of 58 million euros.
The final name in the top 10 is another club that has been relatively quiet in the close season because of FFP. Paris Saint-Germain could still afford a star arrival, though, with David Luiz joining in the club's only permanent deal, worth almost 50 million euros.
Interestingly, all but one of the top 10 are English and Spanish sides, with Germany's Borussia Dortmund the 11th-highest spender and Italy's Roma in 12th.
