LEADERS Shaheen strengthened their claims for the men's First Division title at the expense of defending champions Club yesterday with a tough 1-0 victory at Happy Valley. The match was a physical encounter with four yellow cards handed out - two for each side - and saw Club captain Chris Bredbury come off injured in the first half with a cut left eye after being accidentally struck in the face. Bredbury returned late in the game but was unable to prevent his team's third defeat of the season. ''We had our chances but we didn't take them while Shaheen made the most of theirs,'' said Bredbury. ''We played well but it was not enough. Our hopes of the league title are over and we'll now have to concentrate on the Holland Cup.'' Nawab Ali Khan scored the vital goal. The Sports Road side had three precious points docked last week for fielding unregistered umpires. And another three points dropped to Shaheen condemned Club to fifth spot on 38 points, 12 behind Shaheen with four matches left. In an exciting and physical tussle, Shaheen opened the scoring in the 50th minute when Khan picked up a neat through ball before darting into the 'D'. The former Hongkong international rounded goalkeeper Chris Watson before neatly flicking it into the net after skilfully rounding goalkeeper Chris Watson. Salim Mohammed had come close to opening his club's account in the first half when his flick struck the bar but Club also had chances with four short corners going to waste. Club's Derek Bailey and Tony Weiss and Shaheen's Salim and Sherullah Khan were sent off for five-minute ''cooling off'' periods for rough play but the crowd were treated to some superb play from both sides. It was also sweet revenge for Shaheen who were thrashed by Club 3-0 in the quarter-finals of the Holland Cup two weeks ago. Shaheen had also handed Club a 4-1 league defeat in October. Kowloon Cricket Club kept the pressure on Shaheen when they defeated Nav Bharat 2-1, also at Happy Valley. KCC stay three points behind the leaders, having played a game more. Pakistan Association were the biggest winners of the day thrashing KNS 4-0 at King's Park to remain third while Football Club B overcame struggling Pasbaan 2-0 at the same venue. Second-from-bottom Khalsa continued a comeback, defeating mid-table British Forces 1-0.
