Mali's Seydou Keita has dedicated his goal that won the Spanish title for Barcelona to his wife, children and all the club's fans.
Keita charged forward to head home Xavi's pinpoint pass to give the Catalan club the lead after 28 mins.
Hosts Levante equalised to make it 1-1 but the point was good enough to secure Barcelona's third straight title.
"What a goal," said the 31-year-old. "I dedicate it to my wife, two kids and all of Barcelona's fans."
"This is a very important day for the fans.
"Now we need to prepare for the Champions League final, which will be very important as well and which this club deserves to win."
Barcelona can complete a memorable double should they beat Manchester United at Wembley on 28 May.
Pep Guardiola's three-year reign as coach has brought Barca nine trophies including three league titles, one European Cup and a King's Cup.
Real Madrid will finish as runners-up for the third season in a row, although Barca's bitter rivals did win the Copa del Rey in April.
Much of Barcelona's success in recent years has been built on the phenomenal abilities of Lionel Messi.
The Argentine has weighed in with 31 league goals this term, although he trails top league scorer Cristiano Ronaldo of Real Madrid by five.
And Keita revealed that Barca were desperately trying to add to Messi's tally on Wednesday.
"We have tried everything but Leo wasn't able to score," said the former Seville midfielder.
Keita joined Barcelona in 2008 and has won a host of trophies since with the all-conquering side.
