Croatia made a winning World Cup start against Nigeria, as Oghenekaro Etebo’s own goal and a Luka Modric penalty decided a poor Group D match in Kaliningrad.

Etebo, who joined Stoke City from Portuguese club Feirense for £6.35m on Monday, turned Modric’s first-half corner into his own net after Ante Rebic and Mario Mandzukic had both got touches.

Modric then converted a 71st-minute penalty – Croatia’s first shot on target – after William Troost-Ekong had manhandled Mandzukic at a corner.

Nigeria offered little attacking threat, although Dejan Lovren blocked Alex Iwobi’s shot just before half-time, and Odion Ighalo glanced a Brian Idowu cross straight at goalkeeper Danijel Subasic.

Victory takes Croatia top of their group, after Iceland held Argentina 1-1 earlier on Saturday. (BBC Sport)
