BARCELONA, Spain -- Lionel Messi paid tribute to Diego Maradona by stripping off his Barcelona top to reveal a shirt for the fallen Argentine great after he scored the final goal in a 4-0 rout of Osasuna on Sunday.
Messi celebrated his powerful strike from outside the box by taking off Barcelona's blue-and-burgundy to reveal the red-and-black of Maradona's shirt from his stint at Newell's Old Boys. Messi then blew a kiss with both hands to the sky as he looked upward.
After the game, Messi posted a photo of his tribute alongside an older image of Maradona in the same shirt, adding the message "Farewell, Diego" in Spanish.
"It was a great moment," said Barcelona manager Ronald Koeman. "First, for the goal that Leo scored and then for the gesture he had for the death of Diego Maradona. He had surely been thinking of what he would do. For me, it was a great moment in every way."
Messi played for Newell's before he joined Barcelona at age 13. Maradona played five matches for Newell's in 1994 near the end of his glorious playing career that made him a legend in his home country.
Messi had kept his head bowed during the minute of silence before kickoff in the Spanish league game at the empty Camp Nou for Maradona, who died of a heart attack on Wednesday at age 60. Maradona played for Barcelona from 1982-84.
"We have lost Diego, a world idol," Barcelona's Brazil forward Philippe Coutinho said. "Everyone admired him and we will all miss him. (Messi's) tribute was beautiful."
Coutinho also scored for Barcelona, along with Martin Braithwaite and Antoine Griezmann.
The win was only Barcelona's second in seven league matches. It left the team in eighth place with two games in hand. Leader Real Sociedad hosts third-place Villarreal later. Second-place Atletico Madrid is nine points ahead of Barcelona also with two games in hand.
The victory for Koeman's side may have come at the price of losing yet another defender.
Clement Lenglet hurt his lower right leg when it was unintentionally knocked by an Osasuna player in the second half. He had to be helped off by two team doctors. Barcelona was already without three other central defenders due to injury and right back Sergi Roberto.
Barcelona finished the match with midfielder Frenkie de Jong in the centre of its defence alongside reserve team player ?scar Mingueza in his second game for the senior squad.
Koeman said it appears the injury to Lenglet is "not serious" but that he would undergo a medical exam on Monday.
Sergio Busquets returned for Barcelona from a knee injury that had sidelined him for two games.
Considered by many as the best player in his generation -- and one of the greatest ever -- Messi has been judged, especially back home, by how his career compares to that of Maradona.
Messi shares the lower centre of gravity, the supreme dribbling skills and the ability to score eye-popping goals as Argentina's other great No. 10. But while his life focused on football and family has kept him well clear of the addictions that ruined Maradona's health, Messi has never been able to reproduce the 1986 World Cup trophy Maradona led his country to, coming closest in 2014 when a Messi-led Argentina lost in the final to Germany.
Messi's tribute to Maradona overshadowed a fine performance by Griezmann, the France forward who has been criticized for not reaching his potential at Barcelona.
Braithwaite scrambled in a rebound -- after Coutinho's attempt was saved by Osasuna goalkeeper Sergio Herrera -- to open the scoring on the half-hour mark.
Griezmann doubled the lead three minutes before halftime when he volleyed a blistering strike from outside the area that left Herrera flat-footed and with no chance of stopping it.
Griezmann then passed up another scoring chance and opted to assist Coutinho to tap in the hosts' third goal in the 57th. Messi rounded it off with his strike from long range in the 73rd.
"It was important to get this win because those at the top of table keep winning and we couldn't slip again," Griezmann said. "We did not know what Messi had planned to honour Maradona. It was a nice surprise."
