Graham Potter faces his biggest team selection since joining Chelsea tomorrow when he attempts to pick a team to beat Borussia Dortmund in the Champions League.
He saved his job for now at the weekend after a 1-0 win over Leeds United, as he rolled the dice with a new system for the Premier League game.
The manager returned to a back three system in an attempt to get the best out of some of his important players, and it seemed to do the trick at just the right time.

However, there will only be more importance placed on tomorrow’s game against Dortmund, with the fate of their entire season on the line.
The Blues are tasked with overturning a 1-0 deficit from their first leg, where they were punished for not taking their chances particularly in the first half.
One position Potter faces the biggest dilemma in choosing is in midfield, and in particular who should partner Enzo Fernandez.
Zakaria should start against Dortmund
Chelsea did find joy partnering him with Mateo Kovacic against Leeds, with the pair benefitting greatly from the new system.
Previous duos that have involved the likes of Conor Gallagher and Ruben Loftus-Cheek have simply not worked.
One midfielder he is yet to feature alongside is Denis Zakaria. The Swiss international has been enduring his own road to recovery this year.

He looked the best player on the team in the weeks following the World Cup, before he was forced off injured against Fulham.
He made a return off the bench in the last two games, and has instantly shown a defensive ability the majority of other midfielders at the club don’t have.
Fernandez’s limitations are known, and Zakaria is the one to help hide those in the club’s biggest game of the season so far.
