Celtic B defeated Partick Thistle 4-0 to reach the Glasgow Cup final. 

Stephen McManus' side opened the scoring 17 minutes after young midfielder Tsoanelo Letsosa won the ball back high up and the pitch and made no mistake as he finished calmly.

Just over 10 minutes later, Celtic doubled their lead as Letsosa netted his second of the match to finish a brilliant passing move down the left-hand side of the pitch.

After going into the break 2-0 up, the visitors began to grow into the match more during the second 45 minutes.

They were awarded a penalty on the 72nd minute after Letosoa was judged to have handled the ball.

However, Celtic goalkeeper Josh Clarke saved from the spot to keep the young Hoops two goals to the good.

Five minutes later and it was game over as Josh Thomson finished calmly after a superb individual run.

With two minutes left of normal time defender Ben McPherson made it 4-0 to cap off another good team move.

They will face the winners of Rangers B and Queen's Park in the final.
