Lionel Messi needs to score against only Celta Vigo this season to become the second player in history to score against every other team in a single season.
The 25-year-old, who moved on to 42 League goals for the season with a brace last weekend at home to Rayo Vallecano, has so far scored against 18 of the 19 other teams in La Liga this term.
Cristiano Ronaldo became the first player to score against all 19 other teams in the Spanish top flight, when he managed to do so last term for Real Madrid.
Messi can equal him by scoring against Celta at Balaidos in Week 29, whilst the Argentine would also be the first to score against the 19 other sides in consecutive games.
The Barca forward is on a League all-time record for scoring in successive games, having netted in his last 18, with each game against a different League opponent, such is the fixture organisation in Spain.
Before Ronaldo and Messi, Bebeto for Deportivo in 1992-93 and Baltazar for Atletico Madrid in 1988-89 came closest to the feat, both respectively scoring against 18 of the top flight’s 19 other teams in a single campaign.
