After Ronaldinho lost form, Messi became Barça's new star player at only 20 years old, receiving the nickname "Messiah" from the Spanish media. His efforts in 2007 also earned him award recognition; journalists voted him the third-best player of the year for the 2007 Ballon d'Or, behind Kaká and runner-up Cristiano Ronaldo, while international managers and national team captains voted him second for the FIFA World Player of the Year award, again behind Kaká. Although he managed to score 16 goals during the 2007–08 campaign, the second half of his season was again marred by injuries after he suffered a torn hamstring on 15 December. He returned to score twice in their away victory against Celtic in the last 16 round of the Champions League, becoming the competition's top scorer at that point with six goals, but reinjured himself during the return leg on 4 March 2008. Rijkaard had fielded him despite warning from the medical staff, leading captain Carles Puyol to criticise the Spanish media for pressuring Messi to play every match. Barcelona finished the season without trophies, eliminated in the Champions League semi-finals by the eventual champions, Manchester United, and placed third in the league.
