Inter Milan coach Antonio Conte says they must be careful with Romelu Lukaku.
The striker picked up a knock in the 0-0 draw with Champions League opponents Shakhtar Donetsk.
Conte said, "He suffered a muscle problem against Shakhtar, when he kicked the free kick. We need to get him back to his best.
“You know how important he is for us, in a moment when we are without Sanchez too, who carried a problem from the national teal and is not ready yet.
“We are monitoring the situation; we will act for the best of Romelu and Inter. We must avoid craving for immediate recoveries and the responsibility also lies with the players.
“Forcing it can aggravate the issue. I'm very sorry, we needed him in this period, we are recovering others from COVID. We can and must do well anyway."
