Robert Lewandowski's days at Borussia Dortmund may now be numbered, following the news of his pre-contract agreement with title rivals Bayern Munich, yet it's impossible to look at the Polish international's career at the club and not appreciate all that the striker has done for Jurgen Klopp and his side.
From the famous back-to-back Bundesliga titles, the historic DFB Pokal battles with Bayern, to the Champions League final that drew in football fans the world over; Robert Lewandowski has been with Dortmund on this wonderful journey from the very beginning.
5. April 30, 2011 - Bundesliga: Dortmund vs. Nurnberg
It seems fitting that we begin our countdown with a goal that concluded Dortmund's first season as title contenders and ultimately led to the club's first Bundesliga title in nine years. Lewandowski's first goal of the day made it 2-0 for his side, giving them all three points and ensuring that the title was finally out of Bayer Leverkusen's grasp with two weeks to spare.
4. June 12, 2012 - DFB Pokal Final: Dortmund vs. Bayern
The next goal, or trio of goals, come in the form of a cup final between Germany's two biggest sides. Dortmund were just weeks after winning their second Bundesliga title and all that stood between them and a domestic double were second-placed Bayern with high hopes of stealing a cup final from the retaining champions. Alas such luck wasn't with the Bavarians that day as Lewandowski put an inexperienced Jupp Heynckes' side to the sword with three fantastic goals.
3. April 9, 2013 - Champions League: Dortmund vs. Malaga
Many forget just how close Dortmund came to elimination in last season's Champions League run, when La Liga side Malaga came to the famous Westfalenstadion and looked as though they were all but set to match Klopp's side and sneak a late away goal. Yet it was a piece of magic from Marco Reus in the form of a twirling back-heel pass that put Lewandowski on his way. All that was left to do was chip the keeper and knock the ball in to the back of the net. A goal deserving of such an illustrious competition.
2. May 11, 2012 - Bundesliga: Dortmund vs. Bayern Munich
The pinnacle showdown of the 2011/12 title race between Dortmund and Bayern came down to a single game in early May at the Westfalenstadion, with Bayern trailing Klopp's men by just three points in the league. If Bayern could sneak a win here the momentum of the entire season would shift and it would be Heynckes' men in the driving seat as both sides turned the final bend of the championship.
Yet that day belonged to Dortmund and as they continued to assault Manuel Neuer's goal, the breakthrough finally came 12 minutes from time through the strangest of circumstances. A scuffed shot from Kevin Grosskreutz, following a corner to Dortmund, found its way strolling down the middle of the six-yard box on course for Neuer's grateful arms, before Lewandowski struck, as he always does in such a danger area, and knocked the ball on with his heel in to one of the corners. Lewandowski had scored, Dortmund had won. A week later Bayern dropped points to Mainz and Dortmund where out of reach. The Bundesliga title was theirs again.
1. May 24, 2013 - Champions League: Dortmund vs. Real Madrid
Although Dortmund fans will never forget the experience of reaching Wembley stadium for the Champions League final in 2013, it was the semifinal match against Real Madrid that will forever be remembered as the evening Europe and the world football welcomed Lewandowski to stardom.
His hat-trick of goals in the first-leg tie in Dortmund was an individual performance that is rarely seen from players in the modern era. To score three goals and effectively knock Madrid out of the Champions League semifinals is a talent that safely ensured the striker as worthy of any club across the continent.
Yet it is Lewandowski's final goal that night that we all remember so well. From the scuffed shot-turned-cross from Marcel Schmelzer that bounced between three Real Madrid players across the six-yard box before reaching our star striker, who then pulled back just in time to avoid the full-stretch of Pepe's slide tackle, to the final swing of his foot that ensured Dortmund's place in the final of the European Cup. The entire move was nothing but sheer instinct and the perfect example of this player's ability. A world-class goal, on a world-class stage, from a world-class striker.
