The Borussia Dortmund star started as a lone striker for Poland against Greece in the opening game of Euro 2012 and showed Manchester United fans what they could expect at Old Trafford next season with a well-taken goal.
In the build-up to the game against Greece, Poland coach Franciszek Smuda claimed Lewandowski is on the verge of a move to Old Trafford after the tournament.
The 23-year-old striker, known as 'Lewy' to his team-mates, was in sparkling form for Dortmund last season heading into the European Championship.
He had joined Dortmund from Lech Poznan in 2010 after averaging a goal every two appearances, and he has continued to find the net on a regular basis since.
Named the Bundesliga's Player of the Year for 2011/12, Lewandowski scored a sensational hat-trick in the German Cup final against Bayern Munich, helping Dortmund to secure the League and Cup double.
Lewandowski was always likely to be Poland's main goal threat and he helped get the co-hosts off to a perfect start, scoring inside 18 minutes at the National Stadium in Warsaw.
The six-foot striker was in the right place at the right time to head home Jakub Blaszczykowski's delicious right-wing delivery to send the crowd into a frenzy.
However, in the second period, Lewandowski failed to make an impression, partly due to a lack of service from the flanks, although he came close to snatching a winner when he sliced his right-foot effort into the side netting.
The player is set to enter the final two years of his current deal and contract talks with Dortmund reportedly broke down last month.
If he can just add another dimension to his play, then it will be just a matter of time before Europe's elite come calling.
