The Argentine attacker netted against Valencia yesterday, reaching the astonishing milestone.
The strike at the Camp Nou ensured that Luis Enrique’s men maintain their lead over fierce rivals Real Madrid at the top of the La Liga table, but also brought up a personal milestone for the four-time Ballon d’Or winner.
Messi’s strike was the 400th of his Barcelona career, with the South American forward continuing to go down in the record books for his goalscoring ability.
The 27-year-old took to Facebook following the game against Valencia to thanks fans for their messages of congratulations and pledged to score lots more goals for the Blaugrana.
The strikes was Messi’s 35th in La Liga this season; an incredible tally, but it still pales in significance to the 50 league strikes he netted in 2011-12.
Barcelona are on track for a momentous treble this season, with a chance to win the Copa del Rey final against Athletic Bilbao and the Catalans also looking odds-on to make the Champions League semi-finals after a win against PSG in Paris in midweek.
