According to midfielder Ki Sung-yeung, Celtic must forget the pain of the 3-1 loss to Rangers and look ahead to Wednesday's Co-operative Insurance Cup quarter-final against St Johnstone in Perth. With a league cup semi-final place up for grabs on tomorrow night, Ki is putting events at Parkhead behind him and looking ahead to McDiarmid Park in Perth. Ki said: "I feel very disappointed because we scored the first goal, but gave them three goals in 20 minutes in the second half. We suffered because of a lack of concentration and we made mistakes. But the game has gone now and we have to concentrate on our next game against St Johnstone." |
