Graham Potter was lucky enough to have an almost fully fit Chelsea squad for his first match against RB Salzburg but there were warning signs of the upscaled management issues he will have.
With Mateo Kovacic - who has only played 131 minutes of league football this season - back fit there was a boost in midfield and N'Golo Kante remains the only outfield player missing. It meant that Potter could implement widespread early ideas as to what he wants to do at Chelsea, but one worrying moment will bring him back down to Earth.
As much as the tactical switch in midfield and with Raheem Sterling largely worked, two big positives from Potter on the night, the mistake by Thiago Silva was a concern. Not because he made a mistake, they are rare enough and could have still been stopped before and after his poor sliding tackle, but more because of what it could mean going forward.
