Jason Denayer believes that Aberdeen's title challenge can help Celtic's efforts in three cup competitions.
After a seven week injury absence, the on-loan Manchester City defender returned to partner Virgil van Dijk in the centre of defence as Celtic won 2-0 away to Hamilton Accies on Saturday.
With Aberdeen drawing 3-3 at home to Dundee their lead at the top of the SPFL has been trimmed down to two points with Celtic having two games in hand.
Over the last few seasons Celtic have normally enjoyed a double-digit lead at this stage of the season but with February bringing cup ties in the League Cup, Scottish Cup and Europa League, Denayer is happy that there is a genuine challenge for the SPFL title.
"We need to win every game, we have to focus on playing every match to the maximum," the defender stated.
"Each game is competitive for us, we have to play at our best in the league games and that will help us in the cup competitions.
"If we had a big lead we could maybe get away with being less than 100 per cent in the league but we know that isn't the case."
Celtic can go to the top of the table by beating Motherwell at home on Wednesday night but the future of Kris Commons is likely to dominate the coming days.
Despite Deila's denials fresh rumours of a move to join Neil Lennon at Bolton seem to emerge on a daily basis.
At the final whistle on Saturday Commons threw his boots to the Celtic support with many fans seeing that as a farewell gesture.
The former Derby man is no longer the 'first pick' that he was under Lennon and is out of contract in the summer when he turns 32.
Celtic are believed to have only offered a one-year contract, with another 12-month option, while a two-year deal is on the table from Bolton, although finding a €300,000 transfer fee could be a problem for the Championship side.
Retention rather than recruitment is Deila's priority during the January transfer window with the Celtic boss at pains to state that Commons won't be leaving this month.
"He will not go, I've said it many times that he will not go," Deila said. "We are going to keep all the players we have here for the season so he needs to get new boots- it's going to be expensive for him.
"Even if he says he is not signing a contract, he is going to stay anyway. It's not easy to replace Kris, the decision will not be taken out of my hands."
