Celtic overcame dogged Dundee United to lift the Scottish League Cup and earn the first leg of a potential domestic treble.
Kris Commons and James Forrest scored the goals that broke United's resolve.
A little of the spirit of Jackie McNamara's side was lost when they were reduced to 10 men after captain Sean Dillon's dismissal in the 56th minute.
Celtic were leading 1-0 at that point, while Forrest saw a late penalty saved by Radoslaw Cierzniak.
