Chelsea head coach Thomas Tuchel has acknowledged that he expects Romelu Lukaku and Timo Werner to spend time on the sidelines through injury.
Despite the Blues cruising to a 4-0 victory over Malmo in the Champions League on Wednesday night, Lukaku and Werner were both withdrawn before half time.
Lukaku suffered an injury to his ankle in a challenge which won his side a penalty, while Werner pulled up with a hamstring problem 20 minutes later.
While being unable to give a specific timeframe for their returns, Tuchel suggested that both players would miss Saturday's Premier League with Norwich City.
Speaking to BT Sport, Tuchel said: "We have a twist of the ankle for Romelu, and muscle injury and hamstring for Timo, so they will be some days out I guess.
"Normally we are in a good place injury wise, only Christian Pulisic is out, but we miss everybody. We have a lot of games, lot of competitions, so now we have to deal and find solutions, no excuses.
"The two were in good shape, they are dangerous and can create and score so now we need to find solutions and guys who waited for their chance need to step up and score. The race is on, the guys who start against Norwich have our trust and we will try to find new solutions."
Chelsea play five games in the space of 15 days before the next international break.
