Celtic manager Brendan Rodgers has admitted it will be difficult for his side to keep up continual intensity in performances given their hectic fixture schedule.
There is no winter break in Scottish football this season meaning, since they returned from the November international break, the Hoops, more or less, have multiple games per week all the way through until March.

Rodgers’ squad depth has already been put to the test and continually will be as the Scottish Premiership champions march on.
At Tannadice on Sunday, we saw the first real domestic dropoff from Celtic this season as they faltered to a lacklustre goalless draw with Dundee United.
They will look to bounce back at home to Motherwell later this afternoon, but Rodgers has admitted every display this season won’t be up to the mark: “It used to be amazing to have that break,” he said (The Celtic Way).
“We would all love to play 90 minutes of high-intensity football in 60 games a season, but that’s not humanly possible.
“Sometimes you just have to grind out the wins, and more often than not, this team have done that.”
Celtic have a habit of scoring when it matters domestically and winning regardless of the performance.
They didn’t on Sunday, but back-to-back home games this week provide them with the perfect opportunity to get back on track.
First up is the Steelmen today before St. Johnstone come to Celtic Park on Sunday.
Maximum points would be much welcomed by Rodgers and Co. before the new year Glasgow derby at Ibrox comes into view.
