MADRID — Real Madrid forward Cristiano Ronaldo could be sanctioned for his goal celebration when he netted the equalizer in Sunday's La Liga ‘Clasico' at Barcelona, the president of Spain's professional soccer league (LFP) said. Ronaldo, not for the first time when he has scored at the Nou Camp, appeared to be urging the Barca fans to calm down when he struck to make it 1-1 in the 31st minute. The Portugal captain has gained a reputation for winding up opposing fans and was widely criticized when he tore off his shirt to celebrate his successful penalty in last season's Champions League final victory over Atletico Madrid. “We have to be careful with provocative gestures by a player when he scores a goal or with any other provocation or conduct that could incite violence among spectators,” LFP president Javier Tebas told reporters Tuesday. “It must be sanctioned, from a fine up to a suspension,” he added. Messi tops list of richest players Lionel Messi tops France Football magazine's list of richest players for the fifth time in six years after hitting an estimated 65 million euros ($71.3 million) in revenue last year. The Barcelona forward edged Real Madrid midfielder Cristiano Ronaldo in the list, with Barcelona striker Neymar, Paris Saint-Germain defender Thiago Silva and Manchester United forward Robin Van Persie completing the top five. The French magazine, which ran its survey for the 17th time, makes its estimations by adding salaries, bonuses and advertisement revenues. According to France Football, Ronaldo earned 54 million euros ($59.2 million) last year, while Neymar cashed in 36.5 million euros ($40 million). A total of 12 players, including Gareth Bale (Real Madrid) and Wayne Rooney (Manchester United), earned more than 20 million euros ($21.9 million) last year. — Agencies
