3 talking points as Celtic stretch lead over Rangers thanks to Giorgos Giakoumakis hat trick against Dundee

Hat-trick hero Giorgos Giakoumakis turned Celtic's saviour to sink resilient Dundee with a dramatic late winner.

Ange Postecoglou's side cut it fine to stretch their Premiership lead over Rangers to three points in a five-goal thriller with the Premiership's bottom side.

Mark McGhee very nearly opened his unfancied Dens Park reign with a draw in Glasgow but the Greek striker struck with just minutes remaining to claim all three points.

Dundee had led through Danny Mullen early on before Giakoumakis produced a quick-fire double to turn the match on its head.

But Ryan Sweeney pegged Celtic back again, popping up with a powerful header to set up a grandstand finish that was eventually settled by Giakoumakis.

Victory pushes Postecoglou's team further clear of the reigning champions after they slipped up to draw at Tannadice earlier on Sunday.

The Celtic boss recalled Giakoumakis and Reo Hatate after a midweek Europa Conference League defeat while McGhee was without injured captain Charlie Adam.

His five at the back setup ensured it didn't take long for proceedings to fall into the expected pattern, with blue shirts setting up camp on the edge of their own box.

Celtic pushed and probed and it took around 20 minutes to some excitement around Parkhead as Reo Hatate controlled a high ball and looped an effort over Ian Lawlor's crossbar.

What it needed was proverbial cat among the pigeons to either entice Dundee out or elevate Celtic's sense of urgency.

The latter may have been the outside bet but it was Danny Mullen who stunned Celtic Park into silence as he swept home Paul McMullan's corner at the back post.

Now was the time for the Dark Blues to really dig in but within 14 minutes they were not only level, but behind.
