#4 Hit: Lautaro Martinez
Martinez broke the deadlock with a clever, pinpoint finish sliding across the turf wrongfooting ter Stegen at his far post, having impressively held off Clement Lenglet's best defensive efforts to devastating effect so early on.
This set the tone during an impressive first-half showing by the visitors, who took the game to Barca and made them uncomfortable out of possession - while equally hesitant with it, given their deep block, three experienced centre-backs and the rigidity Conte instils among them.
If not for an excellent point-blank save by ter Stegen, the Argentina international would have doubled Inter's lead before half-time. Leading the line confidently with Alexis Sanchez buzzing about to his right, he's showing the capability to succeed Mauro Icardi as their lone centre-forward, which is impressive considering how things have changed so much in 2019.
Barca themselves have been linked with an approach for the 22-year-old, as a long-term centre-forward successor to Suarez. Performances like these certainly don't hurt his stock, even though he'll gladly tell you of his commitment to the cause under Conte.
