Celtic fans unveiled a banner directed at Rangers striker Alfredo Morelos during their 4-0 victory over Motherwell on Wednesday night.
The Parkhead side ran out victors thanks to a double from Odsonne Edouard and goals from Leigh Griffiths and Callum McGregor, and their fans were in full voice throughout.
A closer look at the away end at one stage, however, revealed a banner emblazoned with the words 'MEJORATE PRONTO ALFREDO' - or 'get well soon Alfredo' for those not versed in Spanish.
The banner could be a direct reference to one Rangers fans infamously directed at then- Kilmarnock manager Steve Clarke back in February.
The current Scotland boss was subject to a 'get well soon, Steve Clarke' jibe after he had complained about sectarian chanting from sections of the Rangers support.
The use of Spanish in the banner may also be a subtle nod to the recent situation involving a poorly-translated interview with Sky Sports which has dominated the headlines.
The news outlet have recently apologised after attributing quotes to the striker which accused sections of the Celtic support of using racist slurs, quotes which were later found by the Daily Record to be misleading and in some cases false.
They have since taken responsibility, publishing a separate, corrected translation which heavily differs from the original.
