In recent weeks, Ange Postecoglou has been able to rotate the squad as he pleases, which is paying off for Celtic.
Going back just over a month ago, there was criticism directed at the Celtic boss for the number of changes he made going into the league match against St Mirren before the international break.
At that point, he may have believed that the squad was at the point of where it is now, with rotation being seamless. A big part of that will be down to players getting more minutes in their legs which some rhythm appearing back in the Celtic team.
After hammering Hibs 6-1 at the weekend, nobody who scored at the weekend started at Fir Park, with the Celts running out 4-0 victors.
Even after scoring a brace last night against Motherwell, Liel Abada may not start at Tynecastle, with James Forrest potentially being given the nod along with Giorgos Giakoumakis.
There were a lot of new additions to the Hoops team during the summer window, with Postecoglou knowing that a big squad was needed to compete in four competitions with a winter World Cup on the horizon.
It’s becoming extremely difficult to predict what eleven the Hoops boss will play, which must be causing opposition managers a real headache.
With news that plans are already well underway for the January transfer window, it will be fascinating to see whoever else Postecoglou adds to the team.
