Multiple Celtic defender signings tipped after latest development - Whelan

Noel Whelan has slammed the “schoolboy errors” by Celtic against Ross County and tipped multiple defending signings this summer.

Speaking exclusively to Football Insider, the former Aberdeen striker suggested there will be “a few changes” in the team’s backline after yet another wretched display.

The Hoops dominated possession and had 20 shots on the Staggies’ goal but were beaten by a Jordan White header in the 71st minute.

Manager Neil Lennon called the goal “inexcusable” as his side slumped to 18 points behind league leaders Rangers.

Their Glasgow rivals now need just seven points to win the league meaning they could wrap up the title at next month’s derby at Parkhead.

“It’s schoolboy errors again,” Whelan told Football Insider correspondent Dylan Childs.

“It’s certain things letting the team down defensively. You’ve got to look at that again as one of their weaknesses this year when they’ve been so strong in other seasons. I can’t quite put my finger on it, I’m not too sure why.

“It’s just players not doing their job properly and a lack of concentration.

“We talk about certain things that need to change, people’s attitude and desire.

“There’s going to be a few changes in defence in the summer, new signings, because it seems to me people have been a bit lacklustre in doing their jobs right – a bit too comfortable.”

Lennon also said after Celtic’s second defeat to County this season: “Our defenders don’t seem to want to defend this season.

“We do the work on the training pitch but if the players don’t attack the ball there’s not much you can do.”
