In October 2000, Jesper Grønkjær joined Premier League club Chelsea for £7.8 million, which made him the then most expensive Danish football player. However, he was still sidelined with an injury until January 2001. His career at Chelsea lasted for four years although his form during that time was somewhat inconsistent. At his best he was a constant threat; creating and scoring some very important goals for the club. But his most notable Chelsea performance came against Liverpool on the final day of the 2002–03 season, assisting with the first goal and scoring the second at Stamford Bridge to give Chelsea a 2–1 victory and fourth place in the league, which allowed the club to qualify for the upcoming 2003–04 UEFA Champions League tournament. The importance of this result cannot be overstated, as qualification for the Champions League was considered essential to Roman Abramovich's impending takeover of the club, which was at the time in some financial difficulty. For this reason, it is often referred to as the "billion pound goal." Talking about the match in February 2011, Grønkjær said "I remember the goal very well. I was on the right wing when we got a throw-in, but instead of passing I cut in from the right and beat three or four defenders before sticking it in the other corner. It was a nice feeling, and a good reward for a great season."
