Whilst just a few weeks ago the Chelsea line-up seemed to pick itself, there are doubts over many positions now.
Following a run of two defeats in three games, Maurizio Sarri has a lot of questions regarding a number of players.
On the other hand, Manchester City have looked blisteringly good in the Premier League so far.
They remain undefeated in the league and top of the table after beating Watford 2-1 on Tuesday night.
So, let’s have a look ahead at some of Sarri’s selection decisions:
Loftus-Cheek to keep his place?
Having been a part of Gareth Southgate’s England side in Russia, Ruben Loftus-Cheek has struggled for playing time at Chelsea.
But just recently, there have been signs that Sarri has started to trust the England international.
He came on and scored against Fulham on Sunday and got another goal against Wolves on Wednesday.
Although Sarri seems to favour Mateo Kovacic, Loftus-Cheek should maintain his starting position.
Christensen or Luiz?
David Luiz has been Sarri’s centre-back of choice in the Premier League.
But after numerous defensive errors, the Italian manager finally lost patience with Luiz and relegated him to the bench.
Andreas Christensen got a start in his place, having previously only started in the cup competitions.
Despite performing fairly poorly in the loss against Wolves, Christensen should retain his place.
