Chelsea boss Graham Potter is set to make some of his most important decisions since taking the reins at Stamford Bridge on Tuesday night as he prepares to name a side to take on Borussia Dortmund in the Champions League round of 16. It's the second leg of the tie at home, with the first at the Signal Iduna Park ending 1-0 to the hosts after a solo effort from Karim Adeyemi.
It means the Blues have to turn the scoreline in their favour if they wish to book their place in the final eight of the competition. It won't be easy for Potter to make a decision on how his side may setup for the clash, with a whole host of absences due to a mix of injuries and registration restrictions.
However, the former Brighton manager will have to put those concerns aside to name the best team he can in those circumstances. So with that said, here's a look at three ways Chelsea could line-up to try and beat Borussia Dortmund and book a place in the next round of the Champions League.

Minor tweaks to Leeds clash
If it ain't broke, don't fix it. That's normally a phrase touted when it comes to decisions over the team and Potter could take a similar approach to that when naming his side against Dortmund, drawing on positives taken from victory over Leeds United last time out.
The manager went for a back three for the first time in a while, but due to registration of players, he will be unable to select Benoit Badiashile in the back line. This means Trevoh Chalobah would have to slot in for one change to the side that earned a win at the weekend.
Starting XI: Arrizabalaga; Fofana, Koulibaly, Chalobah; Loftus-Cheek, Fernandez, Kovacic, Chilwell; Sterling, Havertz, Felix.
Reece James decision
One key decision that will have to be made before the game is over the inclusion of Reece James in the side, who is a doubt beforehand. The wing-back has suffered another injury, but could feature as a late decision will be made over whether he can play.
Starting XI: Arrizabalaga; Fofana, Koulibaly, Chalobah; James, Fernandez, Kovacic, Chilwell; Sterling, Havertz, Felix.
Back to a four
With Chelsea searching for a goal in the midst of all their struggles in front of it, the need for more attacking options could require a return to a back four. Mykhailo Mudryk could be included to add pace and width to the side, while Joao Felix would be free to roam around the pitch.
Starting XI: Arrizabalaga; Fofana, Koulibaly, James, Chilwell; Fernandez, Kovacic; Sterling, Felix, Mudryk; Havertz.
