Noel Whelan insisted that Shane Duffy could not have written his debut better himself after the Celtic defender starred on his first appearance for the club.

The former Aberdeen and Leeds United striker, speaking exclusively to Football Insider correspondent Dylan Childs, heaped praise on the 28-year-old for his “absolutely tremendous” start to life in Glasgow.

Duffy, who became Celtic’s latest signing when he arrived on a season-long loan deal from Brighton earlier this month, capped his full debut for the Hoops with a goal and a clean sheet in the 5-0 thrashing of Ross County on Saturday.

The Republic of Ireland international lined up in a back three alongside Kristoffer Ajer and Christopher Jullien despite suggestions one would be dropped to make room for new signing Duffy.

Whelan claimed that Lennon may have found the perfect formation to provide both attacking impetus and defensive solidity.

“Duffy getting in on the act on his debut – what a week it has been for him,” he told Football Insider. “Absolutely tremendous.

“It could not have gone any better, even if he had written it himself. What a way to start your career off at Celtic with a goal and clean sheet.

“I think that Lennon will change it around given what he has at his disposal but that formation worked. That formation with those players is very, very affective. You get that bank of five at the back out of possession, still have a bolstered midfield and play two up top.

“You can only play to your strengths but looking at that Neil will be thinking that they can make a real statement in the league with two striker and three solid centre-halves. They will be difficult to break down and exciting going forward.”
