'Dreadful', 'Absolute treat' - This is what Celtic and Rangers fans are saying about Brighton man Shane Duffy

Shane Duffy of Celtic is seen during the Ladbrokes Scottish Premiership match against Hibernian at Celtic Park.

Things aren't going to plan for Brighton & Hove Albion defender Shane Duffy during his loan spell at Celtic.

The Hoops have now gone four consecutive league games without a win for the first time in 21 years, after a second draw in five days against Livingston on Wednesday night.

The result leaves Celtic – who have two games in hand – 20 points adrift of Old Firm rivals Rangers in the title race.

And Duffy, who penned a dream loan move in the summer, has come under fire from disappointed Celtic fans.

@Kearney1085: “When we signed Shane Duffy to be a threat from set-pieces, I thought we meant in the opposition box.”

@Stephen4_2: “Today Shane Duffy gave one of the most inept and incompetent performances that I have witnessed in my 55 years watching Celtic. Absolutely abysmal.”

@jcotter1916: “Shane Duffy is easily the worst centre half I’ve ever seen playing for us... he’s dreadful...”

@sadbhoy_: “Mental that Shane Duffy is living my dream. What’s even more mental is that he is playing exactly like I do.”

Rangers supporters, however, are thrilled with the Republic of Ireland man's performances.

@iJuggernaut6: “I’ve never liked a Celtic player before but that Shane Duffy is an absolute treat.”

@ksc4273: “Would it be wrong to invite Shane Duffy to our end of season awards doo?”

@JW_1872: “Shane Duffy was hyped up as the Irish Maldini when he signed for Celtic. Turns out he’s the Irish Philippe Senderos.”
