IT'S official. English Premiership side and FA Cup finalists Chelsea will play the Hong Kong League XI on May 22 at the Hong Kong Stadium. Chelsea and the Hong Kong Football Association exchanged contracts via fax between the FA headquarters and the London club's Stamford Bridge base for the single exhibition match which will mark the FA's 80th anniversary celebrations. The Blues have promised their FA Cup squad including top striker Gavin Peacock, Republic of Ireland's Tony Cascarino and 23-year-old John Spencer (above), who will be making a return to the territory after a four year absence.
