With seven wins in the last eight games, Celtic are finding their feet under new manager Ronny Deila - and two of his star players continue to hit the headlines.
Midfielder Kris Commons has been sensational ever since his 2011 move from Derby County, scoring 71 goals in 164 games for the Hoops in a stunning spell with the club.
Meanwhile, striker John Guidetti's record now stands at ten goals in 11 games since joining from Manchester City on loan, and the Swede has already become a crowd favourite at Celtic Park.
Yet both are out of contract at the end of the season, though Guidetti's registration remains with Manchester City. That means that both players are free to sign for other clubs in January on pre-contract agreements - a huge concern for Celtic given their importance.
Assistant manager John Collins confirmed earlier this week that talks are underway to keep Commons and Guidetti at the club, but former Hoops striker Chris Sutton is concerned.
With 86 goals in 189 games, Sutton was adored in Glasgow, forming a superb partnership with Henrik Larsson in the process - but he says the club will be showing a lack of ambition if they fail to keep both Commons and Guidetti.
"There comes a time when you look at the stadium being half full where Celtic are going to have to show some intent. Fans go to matches to watch players and top players get bums on seats," said Sutton.
"What would happen if they let Commons go and if Guidetti doesn’t sign? What message does that send out to the Celtic fans? It is important that Celtic show intent and try to get Commons and Guidetti signed up – and then add to that if possible."
"I know we also have to be realistic in the marketplace that Celtic are buying from but that is the challenge. The fans want to see progression and want to see Celtic getting stronger to give them hope. It does not send out a good message if Celtic let Commons virtually walk away which is what he would be doing," he added.
Fans could accept signing one and losing the other, but if both end up leaving the club permanently, supporters will begin to question what direction the club is heading in - making it imperative that Celtic secure the futures of both players.
