Kenny Miller admitted that Rangers players were "ashamed" and "embarrassed" after their record 5-1 home defeat to Old Firm rivals Celtic.

The 37-year-old Ibrox captain, who signed a new one-year deal on Friday which takes him to 2018, scored the Gers' goal against the Ladbrokes Premiership champions but it was no more than a consolation.

In what was a complete mis-match, an early Scott Sinclair penalty started the rout before goals from Leigh Griffiths, Callum McGregor, Dedryck Boyata and Mikael Lustig took Brendan Rodgers' side a staggering 36 points clear of the third-placed Light Blues.

In a Rangers TV interview, Miller was asked how the players were reflecting on the defeat.

He said: "I think it goes without saying it is disappointing.

"Ashamed. Embarrassed, by the scoreline and performance.

"I don't know what else you can say about a game like that.

"Second best all over the park.

"The lads put effort in, they tried their best but the quality was not where it should be and that emphasised the gulf and it is something we need to address very very quickly."
