STUART KETTLEWELL, the Ross County co-manager, admitted his disappointment at his team’s reaction immediately after Odsonne Edouard had scored a minute into the second-half at Parkhead yesterday.
The Frenchman’s strike doubled the Hoops’ advantage after Mohamed Elyounoussi had given them an early lead.
It was still 1-0 at the interval, but Edouard’s goal opened the floodgates and the 21-year-old frontman scored again while Scotland internationals Callum McGregor and James Forrest chipped in with others as the champions raced to a 5-0 advantage in nine blistering minutes.
Elyounoussi ended the misery with a sixth as Neil Lennon’s men stormed back to the Premiership top.
Kettlewell, speaking to BBC Sport, admitted: “The message at half-time was reasonably positive.
“The greatest disappointment for us was how we conceded the second goal and the reaction after it.
“We don’t feel we dealt with the situation, the atmosphere and the quality Celtic have got.”
The shell-shocked Dingwall outfit have now slipped to sixth place, but remain within four points of Motherwell in third place.
The Fir Park side slumped to a shock 3-0 defeat from Aberdeen in Lanarkshire while the Highlanders were being put to the sword in the east end of Glasgow.
