Cahill did not play in either of the Champions League last-16 legs with Barcelona or Carabao Cup semi-final legs against Arsenal and was also absent for recent Premier League clashes with Manchester City, Manchester United and Tottenham Hotspur.
The centre-back has struggled for form, losing his place in both the Chelsea and England side. He's in good physical condition.
Meanwhile, Conte says it is unfair to criticise the club for selling Mo Salah after the Liverpool winger emerged as the outstanding player in English football this season.
"We are talking about an important player for Chelsea". He has played big competitions.
"I know when you have to go to play a World Cup or European Championship, it's important to have players with great experience because the pressure will become very strong for everyone". Having started regularly when available for the Three Lions' qualifying matches, after the turn of the year Cahill was deselected by national team manager Gareth Southgate for friendlies with Netherlands and Italy.
The Russian businessman has taken extra of a hands-on roll with the membership in current months and can take an energetic position on who replaces Conte forward of subsequent season. Now I think it's right to give an opportunity to Gary to play more.
"He had this problem in his knee, but he is working very hard and I think he is aiming to come back before the end of the season", the Italian coach added.
