Brazilian Ricardo Rambo stepped down as Sun Pegasus coach on Tuesday, becoming the third manager in the Hong Kong Premier League to leave his post this season. Pegasus started their campaign with five straight wins, but have been unable to maintain their momentum. They were eliminated by minnows Wong Tai Sin in the Senior Shield quarter-finals and the 4-2 defeat by rivals South China in the league on Sunday was the final nail in Rambo's coffin. Yeung Ching-kwong of South China and Cheung Po-chun of BC Rangers are the two other coaches to have already lost their jobs this term. We need to make a change to bring back the players' confidence and resume our attacking style of play Pegasus club director Chan Chi-hong Pegasus club director Chan Chi-hong will succeed Rambo, the second time he has taken up the role after Chan Ho-yin was fired in 2012. "Results always come first in professional soccer and although we are still chasing the three remaining trophies, we need to make a change to bring back the players' confidence and resume our attacking style of play," said Chan. "We have a bunch of quality players and I am sure we can get back on the right track." Pegasus are joint second on the table. They have also reached the League Cup semi-finals, with the FA Cup due to start. Their two league matches against defending champions Kitchee and current leaders Eastern in March will be crucial. To strengthen their defence, Hong Kong international Wisdom Agbo, their captain from 2008 to 2011, will make a return. Agbo was with Harbin Yiteng, who were relegated to China League One last season.
