Celtic striker Leigh Griffiths reveals 'revenge' motivation behind Scottish Cup final win over Hearts
Griffiths replaced Odsonne Edouard in the 97th minute after Hearts had recovered from two goals down to force extra-time at an empty Hampden.
The Scotland striker pounced just a few minutes later to put the Hoops 3-2 ahead, only for Josh Ginnelly to equalise for Hearts and force the game into penalties.
Griffiths then scored from the spot as Celtic claimed a 4-3 win in the shoot-out and the 30-year-old from Leith was delighted to get one over at his former derby rivals.
"I've been humiliated in a cup final against Hearts so I wanted to try and get revenge," he told Premier Sports.
"It might not be a 5-1 scoreline but it's another medal round the neck and I'm absolutely buzzing."
Griffiths also demanded respect for Celtic's historic quadruple treble, insisting: "It's hard for teams to do one treble.
"We've done four on the bounce now and I think we need to get the credit we deserve.
"We've jumped every hurdle that's been in our path and it's something I don't think we'll ever see again in British football.
"We've been criticised and rightly so because performances haven't been great, but hopefully that's a turning point now.
"We've got a few games that we can hopefully pick up three points and we look forward to the big match [against Rangers] at the start of January."
