Celtic are finding the defence of their Scottish Premiership crown to be tougher than many expected.
They are being widely tipped to emerge victorious in that particular battle, but they are being pushed all the way by Aberdeen and Dundee United.
It could, however, be argued that some of the struggles being endured by the Hoops have been self-inflicted.
Andy Walker sees things that way, with the former Parkhead forward of the opinion that Efe Ambrose is doing the collective cause few favours.
He remains confident that success will be toasted come the end of the season, but has warned that Celtic must be wary of allowing complacency to creep in.
Walker told Sky Sports: “They have actually been playing very well, creating a lot of chances. They did that against Dundee United, although they lost the game 2-1. They created numerous chances again against Ross County (in a 0-0 draw).
“They are coming up with a few defensive mistakes – Efe Ambrose is giving teams chances and to be fair to the likes of Dundee United and Nadir Ciftci, they have put them away.
“I think on their day Aberdeen and Dundee United are more than capable of beating the best. The best right now in Scotland is Celtic, but they have to be aware that there is a level of consistency from the likes of Aberdeen that we haven’t seen in recent years. The big question is, ‘Can they do it at the business end of the season?’.”
Having seen a meeting with Partick Thistle postponed due to a waterlogged pitch, Celtic have slipped four points adrift of table-topping Aberdeen.
They do have two games in hand, but may consider that to be a blessing and a curse.
The games are going to start stacking up for Ronny Deila’s side and the last thing they need is for tired legs and minds to start undermining their effort as we enter a crucial stage of the season.
