A confident Chan Siu-ki, who trained with English Premier League side Tottenham Hotspur earlier this season, scored four goals as champions South China thrashed relegation threatened Happy Valley 6-2 in the BMA First Division at Kowloon Bay Park last night. His goal spree took his season's tally to 12, which moves him top of the league's goalscoring rankings, after Sandro, of Citizen, who had shared the lead with Chan on eight goals, failed to score in his team's 0-0 draw with Fourway Rangers at Sham Shui Po Sports Ground yesterday. South China now head the league on 19 points after nine matches, three points ahead of Pegasus, in second. Chan, 24, who also scored a hat-trick against Sha Tin in December, said the secret of his success in front of goal was increased confidence. 'Everything is going very well at the moment as I keep scoring in most of the matches,' Chan said after scoring four goals in one match for the first time. 'I scored 19 goals last season, but did not set any target for this season. I'll just give my best in every match I start and see how it goes. 'It is still too early to say if I can win the top-scorer award at the end of the season; there is still a way to go. I am very happy I'm getting many chances to play because the team is now filled with quality foreign players up front.' However, team convener Steven Lo Kit-sing said Chan had a good opportunity to win the award. 'He has shown great improvement recently and scored some very good goals,' Lo said. 'We will have more matches than other teams because we should be able to reach all the cup final; that's why he has the advantage.' Lo said they planned to send the striker back to Spurs for a month in the summer to help to sharpen his scoring skills further.
