First-half goals from Romelu Lukaku and substitute Thomas Meunier set up a comfortable opening night for Belgium as Roberto Martínez's men proved too strong for a Russia side hampered by injuries.
Match in brief
Billed among the pre-tournament favourites, Belgium betrayed a few early nerves but a typically ruthless strike from Lukaku soon quelled them, the Inter striker pouncing on indecision caused by Dries Mertens' searching cross.
Calm in possession and clinical in and around the penalty area, Belgium kept probing and on 34 minutes they had a two-goal cushion, substitute Thomas Meunier firing in when Anton Shunin could only parry Thorgan Hazard's glorious cross.
Russia's difficulties were exacerbated by the loss of Daler Kuzyaev and Yuri Zhirkov to injuries before the break, but they rallied at the start of the second period, finding space between the lines. The Red Devils were still not unduly troubled, holding them at arm's length before Lukaku wrapped up a 3-0 win late on.
A tournament-ending injury to Timothy Castagne took away some of the gloss, though.

That's how to get the tournament party started! The Red Devils have really set the tone even if the first few minutes were a little nervy. As soon as they got into the game, Belgium showed just why they're many people's favourites.

Russia have three days to recharge their batteries and go again. There is no margin for error now for the next two games – against Finland, victors today, and Denmark.
Romelu Lukaku, Belgium forward: "Our first-half performance was great. We created chances but were a little sloppy in the second half. We made mistakes and we'll have to work on that if we want to go far in this tournament."
Stanislav Cherchesov, Russia coach: "The result seems fair. It could have been closer but for some silly mistakes from us. We've played them four times [recently] now and not beaten them."
Toby Alderweireld, Belgium defender: "There are always nerves in the first game, so it's normal that not everything is perfect. But we were in total control of this game. We were under pressure but handled it in the right way. Whenever you score three times against Russia, you can be happy."
Artem Dzyuba, Russia captain: "We started quite well and thought we could comfortably get a draw. But then a silly mistake changed it all. It was always going to be extremely difficult to get back into the game against such strong opponents."
