Northern Ireland enter Euro 2016 having not conceded in 271 minutes, but they've got a tough test ahead of them today as they try to stop the one-man goal machine that is Robert Lewandowski. 

The 27-year-old Bayern Munich striker scored a joint-record 13 goals in qualifying, equalling the previous best tally held by ex-Northern Ireland striker David Healy. 

And as a team Poland have scored a qualifying-high 33 goals.

I'll eat my hat if this game's 0-0.

Poland finished as runners-up in their qualification group with six wins and three draws from their 10 games.

They finished top scorers in qualifying with 33 goals - 13 by Robert Lewandowski. More on him later.

It is their third successive European Championship finals but they are yet to win a game. They finished bottom on both previous occasions, including at Euro 2008, which they co-hosted.

Breaking news away from this game... 

Uefa has released a statement saying that Russia and England could be thrown out of Euro 2016 if their fans are involved in more violence.

The Uefa executive committee said in a statement it has warned both countries that on top of any sanctions over trouble in Marseille this weekend, "it will not hesitate to impose additional sanctions on the Football Association (FA) and the Russian Football Union (RFU), including the potential disqualification of their respective teams from the tournament, should such violence occur again."

Whilst scouring the archives for photos from the World Cup in Mexico in 1986 - the last major tournament involving Northern Ireland - I found this absolute belter.

The scoreboard against Brazil listed all the players with first names instead of surnames.

Beautiful.

Northern Ireland are in the Euros for the first time in their history - and it's been quite a journey for Michael O'Neill's men.

Few would have given the nation much hope of reaching the finals, after a dismal qualifying campaign for the 2014 World Cup in which O'Neill's men lost to Luxembourg and could not beat Azerbaijan.  

But they topped their Euro qualifying group ahead of Romania to reach a first major tournament in 30 years.

And they are currently 12 games unbeaten, a new national record, and no country competing at Euro 2016 has a longer unbeaten run.
