Overall, Graham Potter will be happy with how proceedings went in Austria as Chelsea secured their place in the knockout stages of the Champions League with a 2-1 win over Red Bull Salzburg.
However, the Blues boss revealed that midfielder Mateo Kovacic had picked up a potential issue in the second half of the Tuesday night clash. The Croatian was substituted in the 68th minute, after scoring the opening in the first half, and was replaced by Ruben Loftus-Cheek with Chelsea ahead.
The west Londoners already have a growing injury list amid a congested fixture schedule. Kalidou Koulibaly, N'Golo Kante, Wesley Fofana and Reece James are all unavailable after picking up unwanted injuries, leaving Potter limited in his selection.

With that being said, football.london has taken a look at the injury concerns Potter faces ahead of the weekend's trip to his former side Brighton.
Mateo Kovacic
It had already emerged over the weekend that Kovacic was still nursing a knee injury that started ahead of the season, while Potter's last two attempts to rest the 28-year-old were foiled as he entered the play within the first half against both Brentford and Manchester United.
His presence in midfield has provided a huge boost to Chelsea in the previous three games and Potter will be hoping the concern is nothing severe.
What Potter said: "Feeling his calf, it was a heavy pitch, a bit of tightness and hopefully it’s not too bad."
Kalidou Koulibaly
The defender was absent from the squad to face United at the weekend after Potter confirmed he had picked up a knee injury in the goalless draw with Brentford. Koulibaly had started four of the last five fixtures due to the injuries suffered by Wesley Fofana and Reece James.
What Potter said: "He just felt his knee at the back end of the game against Brentford. It's not too bad, but it's too soon for him to play in this game.
"We lost Koulibaly, so we can't play him, and then we've got a couple of players returning who recovered against Brentford. Thiago couldn't play in the week.
"So it's a case of managing the load and managing the games and picking a team that can be competitive and hopefully win the game."
N'Golo Kante
Chelsea have announced that N'Golo Kante has undergone surgery on his hamstring after specialist guidance and is expected to miss four months of action, including the World Cup.
The Frenchman hasn't played since August 14 after leaving the pitch with a hamstring injury against Tottenham and will now miss the winter World Cup too. The statement regarding his update stated: "Following a successful operation, N'Golo is now expected to be sidelined for four months."
What Potter said, prior to the announcement: "Historically, there are things which have happened which are a concern, and we need to get the bottom of that.
"It's a setback in the last stage of his rehab, so again that's worrying. But all we can do is get the right diagnosis, the right consultation and then try and help him get back to full fitness and enjoying his football."
Return date: February 2023
Reece James
James has been ruled out for at least eight weeks with no return before Chelsea break up for the winter World Cup. The 22-year-old could miss the competition due to having a protective boot on for four weeks, though there's a small chance he could be included in Gareth Southgate's squad in the hope of recovering for the end of the tournament.
Hours after Chelsea posted that James wasn't undergoing surgery, he tweeted: "The race against time is on… But we won't give up."
What Potter said: "The first thing is he's in a brace for four weeks to stabilise the knee, then it's rehab. So that will take, as we said, around eight weeks. That's the latest."
Expected return date: Unknown
Wesley Fofana
According to French news outlet L'Equipe, Fofana suffered a sprained knee and is set to miss up to four weeks of action. However, Potter doesn't expect the young centre-back to feature before the World Cup break and hasn't given an update since the extent of the injury was announced before playing Wolves.
What Potter said: "He is just progressing where he was. I don't think we will see him before the World Cup."
Expected return date: December 2022
