Celtic confirmed their place in the William Hill Scottish Cup semi-finals with a 4-0 victory over Dundee United at Celtic Park.

Jason Denayer gave Ronny Deila's side the lead in the first half, while goals later in the match from Leigh Griffiths, Kris Commons and Virgil van Dijk secured a second cup victory over United in just four days.

Celtic will now face Inverness Caledonian Thistle at Hampden where the winner will face either Hibernian or Falkirk in May's final.
