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.

Modric and Rakitic let down by off-form forwards

At 33, Modric is facing what could well be his final World Cup - along with striker Mandzukic, who is 32, and midfielder Ivan Rakitic, who turned 30 in March.

The Croatia captain won the Champions League for the fourth time in five seasons with Real Madrid in May, but his run-up to Russia has hardly been smooth.

He has become unpopular in his homeland over a saga that has seen him charged with perjury - an offence that carries the threat of jail - for retracting his testimony in the tax fraud trial of a senior Croatian football official.

On the pitch, though, he has managed to put that to one side and provided the class that guided Croatia to an unconvincing victory.

Both he and Rakitic were excellent in their passing, although the lack of movement among the forwards in front of them often thwarted their ambition.

When Croatia did create chances, it was usually their two creative midfielders who were involved. Modric's fine early cross was guided down by Ivan Perisic for Mandzukic to fire over, while Andrej Kramaric's header looped just over the crossbar from a Rakitic assist after half-time.

Rebic, who scored twice as Eintracht Frankfurt beat Bayern Munich to win the German Cup in May, later volleyed a great chance wide from six yards after Rakitic's sublime pass had freed Perisic on the left.

Modric and Rakitic certainly have the ability to unlock the world's best defences - but they will need help from those in front of them when they face better teams than Nigeria.

Nigeria fails to look the part

Nigeria's striking new home kit, dominated by bright green and white chevrons, proved very popular when it went on sale last month - so it was disappointing to see them in their muted away strip for their opening World Cup match.

By and large, Gernot Rohr's inexperienced team were every bit as subdued as their shirts. Rohr's side impressed in qualifying, finishing top of a group that included Cameroon and Algeria - but the German coach has travelled to Russia with a squad containing 18 World Cup finals debutants, and the players selected struggled on the big stage.

Etebo, despite his own goal, was one of their better performers, producing an excellent second-half pass out to the right that Victor Moses gathered and rolled wide of the near post after cutting inside.

Moses was a threat when delivering set-pieces, although his tendency to go to ground easily when challenged did him little credit.

Ighalo, on his 29th birthday, was isolated as a lone striker - his header from Idowu's cross, in the 59th minute, was the first of just two efforts on target by the Super Eagles, although new Brighton signing Leon Balogun went close to heading in from a Moses corner at the start of the second half.

Arsenal forward Iwobi failed to make a significant impact, and Leicester's Kelechi Iheanacho was unable to inspire a comeback when appearing as a substitute - leaving Rohr to fathom just where his team's goals are going to come from.

No shots on target for 59 minutes - the key stats

Nigeria's Odion Ighalo had the first shot on target in this match in the 59th minute - the longest wait for a first attempt on target in a World Cup match so far this tournament.
Croatia's opening goals at Brazil 2014 and Russia 2018 have been own goals - Brazil's Marcelo four years ago and Oghenekaro Etebo this time.
Nigeria became the first team in World Cup history to concede two consecutive own goals in the competition, with their last goal shipped in 2014, against France in the last 16, also coming in this manner.
Croatia have won their opening game of a World Cup for the first time since their debut in the competition in 1998 (3-1 against Jamaica).
Nigeria have lost each of their past seven World Cup games when conceding the first goal.
Croatia have scored in each of their past five World Cup games, their longest scoring streak in the competition.
Nigeria have lost their past three World Cup games, their longest run since a run of four between 1998 and 2002.

What's next?
