Celtic notched up yet another win on Saturday, defeating St. Johnstone 2-1 in a hard-fought victory at McDiarmid Park.
Celtic play host to Inter Milan in the first leg of their last 32 clash, before heading to the San Siro just a week later - and fans will be hoping for another famous night in Glasgow this week.
It will be a tough task for Celtic, with Roberto Mancini's men boasting a number of top players such as Xherdan Shaqiri, Mateo Kovacic and Rodrigo Palacio.
However, Celtic midfielder Stefan Johansen - who scored the winning goal against St. Johnstone - told BBC Scotland that the Bhoys have great squad depth; and the Norwegian believes it's their biggest strength.
"The competition in the team is so hard now, it's difficult to get in the team and you really have to earn your right to play," Johansen said.
"I think that's one of our strengths now that we can put in new guys and people come off the bench and make an impact, but that's how it should be," he added.
Manager Ronny Deila has big decisions to make on Thursday, and has an array of options in the final third - even with Kris Commons ruled out through injury.
Deila almost exclusively plays a 4-2-3-1 system, and there are a number of different combinations he could use for his attacking midfield trident.
Gary Mackay-Steven, Stuart Armstrong, Anthony Stokes, Mubarak Wakaso and Johansen himself will all be hoping to play a part, whilst in attack, Leigh Griffiths, Stefan Scepovic and John Guidetti will be vying for just the one spot.
