Ronny Deila won't punt Celtic's cash on risky signings and only wants to bet on sure things.

But the Parkhead manager has vowed to start putting down the club's money after so far limiting his captures to a free agent and three loan deals. Jason Denayer, Aleksander Tonev and Jo Inge Berget have all been brought in for a season, with the club securing options to buy on the last two.

Celtic fans have been less than impressed by the lack of money spent on filling the holes left by the departure of the likes of Fraser Forster and Georgios Samaras.

But the manager refuses to splash the cash just to buy approval, explaining they have looked at over 500 players in their quest to get the RIGHT men in.

"It's important in the beginning you don't take the biggest chances," said Deila, who has prioritised signing a striker.

"When you get players in on loan, you get the possibility to see them, and the chance to see your own team. When you know it is right, then you have to use the money."

Deila knows the value of not upsetting the dressing room and added: "There is a lot of money available.

"But if we buy a player for £10m, the salary will be four, five or six times what you get at Celtic. If you pay that, what will happen with the players here?"

Haitian midfielder, Jeff Louis, did tick all the boxes - as SportTimes first revealed in May.

But after agreeing a transfer fee with his club, Nancy, Louis chose to go to Standard Liege - even though they offered less money. Deila accepts such blows are part and parcel of the transfer game.

But he will not alter his initial plan to take his time to assess what is available in their price range - and avoid any panic buys.

Deila does hope to have one more player in to fill the wildcard spot available for inclusion in the squad to face NK Maribor a week tonight, a tie the Hoops expect to go ahead even though Legia Warsaw will have their appeal for reinstatement heard by Uefa today.

The manager explained: "We want to have players coming in, but you need to know that, when you use money, this is going to be a signing who is going to make the team better at once, or a very talented player we know we can get something out of."

But the indications are the serious spending will have to wait until after the games against Maribor, by which time they will know if they have the Champions League group stage money in the bank.

Deila is savvy enough to realise he will not have all of the £10m raised from the sale of Forster - who, he revealed was determined to make the move to Southampton -but does expect to be given a chunk of it to reinvest.

He said: "There's still a long time to go in the transfer window. I know there is money available. And, when I feel it's right to use it, I will use it."
