The Celtic defence have lost their “desire” and it is “driving Neil Lennon nuts”, according to Noel Whelan.

Speaking exclusively to Football Insider correspondent Dylan Childs, the former Aberdeen and Leeds United striker claimed the Northern Irishman will be hoping his back line can perform more like Rangers.

The Hoops have kept just one clean sheet in their last eight fixtures across all competitions.

In contrast their Glasgow rivals Rangers have kept an impressive seven clean sheets in their last eight games.

Asked by Football Insider whether Celtic may look to sign a new goalkeeper to cure their defensive woes, Whelan said: “The goalkeeper’s not particularly been the problem for Celtic, it’s the defending and defenders making mistakes.

“They’ve been slack and maybe lost their desire a little bit, they maybe felt games were too easy.

“Like Neil Lennon said there’s got to be a culture change and they need to get back to that hunger and desire and willingness to keep clean sheets and enjoy it. Very much like what Steven Gerrard’s got with Rangers.

“It’s not about your system, it’s not about a three at the back or four at the back. It’s about these defenders defending properly and cutting out these silly mistakes that must be driving Neil Lennon nuts.

“They can score goals but they’re conceding so many cheap, easy goals and that’s the problem. They are goals that can be defended and avoided so they need to get back to basics.

“Hopefully with a couple of these centre-halves coming back with the international break will give Neil Lennon a better choice and help him get some sort of consistency going with a partnership.”
