Latham & Watkins LLP's Brussels office serves as a hub for the European competition practice, and its team is a regular fixture in industry-shaping mergers, as well as reputationally-sensitive antitrust investigations and litigation. In 2017, Sven Völcker, Michael Esser and others assisted Lufthansa with obtaining EU clearance of its acquisition of a substantial part of Air Berlin’s business. In addition, Joshua Holian and Luca Crocco were part of the international group that acted for Broadcom on the global merger control aspects of its acquisition of Brocade Communications Systems for $5.9bn.  On the behavioural side, in a matter involving the interface between EU competition law and digital goods/online platforms, Lars Kjølbye is leading the advice to Valve Software on the EC's investigation into alleged geo-blocking practices by video games publishers. Matteo Bay and Javier Ruiz Calzado are also recommended. Adrien Giraud joined from Willkie Farr & Gallagher LLP.

Transaction work is one of the core strengths of Latham & Watkins LLP's team, which is led by Matteo Bay. In recent work, the group obtained antitrust clearance for Global Infrastructure Partners’ acquisition of Italo – Nuovo Trasporto Viaggiatori and assisted Bain Capital with the acquisition of 99.9% of Fedrigoni. The group also frequently handles cartel and damages claims cases; it is defending Coca-Cola HBC Italia against a civil damages claim brought by a distributor. Brussels-based Luca Crocco is another name to note.
