( CNN ) As goal celebrations go it was almost certainly unique but Roma captain Francesco Totti had plenty to celebrate . His title challenging side was trailing 2-0 to arch city rival Lazio in the Rome derby before the veteran striker worked his magic in the second half . Totti cut the arrears with a fine angled strike in the 48th minute of the clash in the Olympic Stadium . He then claimed his second and the vital equalizer as connected with Jose Holebas 's curling delivery for an acrobatic finish . In frenzied celebrations , Totti promptly grabbed a mobile telephone from one of the Roma coaching staff and took a 'selfie ' picture of himself . The shot was later posted on the club 's official Facebook page and has gone viral on social media . It was the 38-year-old 's 239th goal in Serie A in his 22nd season with Roma . Neither side could add to its tally in a frantic finale to a fine match . Totti needs another 35 to match Silvio Piola 's all-time Serie A record of 274 , and temporarily drew Rudi Garcia 's team level at the top with Juventus . However , the title holders beat Napoli 3-1 away later Sunday to go three points clear -- their victory down to a pair of stunning strikes from Paul Pogba and Arturo Vidal and a rare goal from Martin Caceres . The earlier draw was a blow to Lazio 's slim title hopes , left nine points adrift in third place . Man Utd stunned . In the English Premier League , Manchester United 's title challenge also suffered a massive setback , losing 1-0 at Old Trafford to Southampton . In a lackluster affair , Dusan Tadic 's second-half goal gave the visitors a vital three points to leapfrog United into third in the standings . Juan Mata wasted two fine chances to level for Louis van Gaal 's side , which was seeing its 11-match unbeaten run ended . Earlier , Alexis Sanchez scored twice for Arsenal who beat Stoke 3-0 at the Emirates to move into fifth spot in the battle for Champions League places . Messi stars for Barca . Lionel Messi set up goals for Neymar and Luis Suarez and scored the clinching third as Barcelona grabbed a crucial 3-1 win over La Liga champions Atletico Madrid . Messi , the subject of speculation about his future at the Nou Camp , also conceded the penalty which gave Atletico hope when he was adjudged to have brought down Jesus Gamez . Mario Mandzukic scored from the spot to cut Barca 's lead to 2-1 , but Messi scored from close range to seal three points for his team which leaves them a point behind leaders Real Madrid . Both Barcelona and Atletico , now four points adrift , has played a game more than Real .
