The Germany international limped off the field in the 3-0 win over Stoke City yesterday following a challenge by midfielder Charlie Adam.
However, the Portuguese coach expects the 23-year-old to make a swift recovery in time for the clash with PSG and holds no grudges against Adam over the tackle.
"I believe he will be okay to play [on Tuesday]," the Portuguese told the club's official website.
"I like aggressive football and I can't get inside the mind of a player to decide if the intention was to hurt or not, so it's fine for me."
The Blues trail their French counterparts in the quarter-final tie going into next week's second leg after being humbled 3-1 at Parc de Princes on Wednesday.
