"But for sure, I hope - it is better not to say for sure - I hope some will be available but for sure some will not be available".
The England global will not be available for Liverpool's crucial game against arch rivals Manchester United this Sunday, and is also expected to be sidelined for next Friday's match against Wolves.
It no doubt annoys Mourinho that Klopp is seen as more progressive and exciting than he is, and there are admittedly flaws in that perception.
"I felt this from the summer, our second position last season was a fantastic achievement, and people thought that because we finished second, the next season you will be in a situation where you are going to try to do better, and to do better than second is to be champion".

Here, AFP Sports looks at how United have been left behind by Liverpool on and off the pitch in recent months.

"I was never interested in the points of Manchester United and I am not today", he said on Friday.
One positive for Mourinho is that United are coming into the game off the back of a victory in the Premier League a resounding 4-1 win against a struggling Fulham side.
"In the league, I think City are looking strong and better than any other team at the moment", Ferdinand added.
Jurgen Klopp's Liverpool now sits at the top of the Premier League table but the German boss has some headaches concerning his side ahead of Manchester United's visit to Anfield on Sunday. "You can be a champion without being champion".
