Celtic stay on treble course

Second-half goals from Joe Ledley, Georgios Samaras, Anthony Stokes and Scott Brown helped Celtic to a 4-0 win against 10-man Dundee United and into a semi-final of the William Hill Scottish Cup against either Hearts or St Mirren.

The home side were on top before defender Robbie Neilson, previously booked for a foul on Samaras, was shown a straight red in the 28th minute for leading with an elbow in an aerial tussle with the Greece striker.

The game turned on that incident and in a one-sided second half the home side were put to the sword.
