Chelsea coach Mauricio Pochettino has admitted the club must be cautious with Armando Broja.
The striker has recovered from the long term knee injury that kept him out for much of last season.
However, he is being eased into game time by boss Pochettino, who wants to ensure the player's long-term welfare is the priority.
He told reporters this week: “We need to wait also. He's close but sometimes you are close but last step is difficult after the injury he suffered. He has trained well, we have hope also.
“That is why we are assessing the squad and all of the things that happen. It is easy to say we need another offensive players, but I think we have offensive players and they need to recover.
“If you bring in a player that is not fit or needs to adapt to the Premier League, maybe you are going to spend the same time you wait for Broja, or Nkunku or Carney. Then you are going to create a mess in the squad.
“That is why we are working really hard to analyse the situation."
