Liverpool: Philippe Coutinho a doubt for Newcastle United match
Liverpool manager Jurgen Klopp has yet to decide whether playmaker Philippe Coutinho is fit enough to face Newcastle on Sunday.
The 23-year-old trained this week but Klopp is being cautious for fear of aggravating the hamstring strain.
The Brazilian was expected to play in Wednesday's game at Southampton but Klopp said the initial timescale for his return was "too optimistic".
"He trained nearly normally but he doesn't feel comfortable," Klopp said.
Coutinho was injured in the final stages of Liverpool's dazzling 4-1 victory over Manchester City on 21 November.
Klopp said the former Inter Milan player "tried everything he could" to feature in the League Cup quarter-final at Southampton, which Liverpool won 6-1.
"We have to take care of this. The muscle is a dangerous thing when you are always on your feet, and when you don't feel comfortable you have to stop," added the German.
"He is training. We will wait. If somebody can tell me he's available for the next game, then he plays, no problem. But yesterday (Thursday) nobody gave me that sign. So we will have to wait again."
