CELTIC have taken a dig at Charlie Nicholas in their latest tweet tonight. The Scottish Champions were on the end of a bizarre rant from the ex-Celtic striker in which he said that Rangers had enjoyed a better window than Celtic, despite 5 Internationalist and 1 Scotland U21 star signing.

Neil Lennon responded to these comments at lunchtime but the Celtic Twitter admin took a brilliant dig at Nicholas, satirising his much maligned ‘I’m sitting here thinking’ catchphrase.

Nicholas’ outburst was bizarre and almost acted in an attempt to get himself from coverage off the back of Celtic’s outstanding transfer window. The ex-Sky pundit was speaking in his Daily Record column as he looks to keep himself relevant.

Elsewhere, Celtic have been dealt a blow with James Forrest being sidelined for up to six weeks with a minor stress fracture on his ankle. This will mean that Forrest will miss the game versus Rangers on October 17 and until November.
