Park Ji-sung
Anderson returned to the first-team for a match against West Ham United on 23 February, but after just 20 minutes of the match, Anderson ruptured the cruciate ligament in his left knee and had to be substituted by Park Ji-sung. He was later ruled out for the remainder of the season, as well as the 2010 FIFA World Cup, after analysis determined that he would be out for the next six months.
