Goals are the most important component in the winning formula for a football match. Without goals, there is no conclusive result to determine superiority between opponents. Due to this, since the advent of football, players who score goals have been highly sought after.
Football matches used to be very high-scoring affairs back in the day, with lesser emphasis on defensive shape, structure or tactics. Games used to have five or six goals scored between the two teams on average, a figure that has reduced in the modern game. With more focus on defense and overall tactics, teams are now more well-rounded than ever before.
This has played a part in increasing the value of one goal to a team. AC Milan in 1990s were masters of defending a one-goal lead as was sufficient to win games. They won the 34-game Serie A season in 1993-94, scoring only 36 goals and conceding just 15.
However, teams have given more importance to scoring goals and outscoring opponents since the turn of the millennium. Big teams sometimes win by four, five, six or even seven goals in the modern game.
With the quality of attacking football and the players that carry it out, teams have been able to rack up a tremendous amount of goals.
On that note, let's take a look at the five clubs with the most goals scored in the 21st century.
#5. Chelsea FC (1156 games, 2227 goals)
