Liverpool manager Jurgen Klopp has also passed comment on Ki-Jana Hoever's performance after the 16-year-old played for 84 minutes at the back.
“I am not sure what you all would have said if immediately from the beginning if our centre-half situation was Fabinho and Ki-Jana; then probably a few very smart people would tell me that I don’t respect the competition or whatever," Klopp said.
“So, we tried to do all the things [we could]. Of course, on the other hand it doesn’t make sense to bring in a 16-year-old boy from the start. You don’t bring him, you wait until he is completely ready, but he did well. He came on and did well. That’s how it sometimes starts - when you are really needed then it is only about if you are good enough and not how old you are.
“He did well, so that was all OK. That’s it.”
Liverpool manager Jurgen Klopp: "[It is Dejan Lovren's] hamstring, is what I heard - without any signs before. I asked everybody, no signs, nothing, just out of the blue, so that’s the decision you have to make.
“I don’t know in this moment how long he will be out.”
I'm still waiting to hear from Jurgen Klopp, I fear that his interview may have been done while we were being fed the fourth round draw. I'll get you his reaction as soon as I can.
Liverpool’s Xherdan Shaqiri has ended on the losing side in all four of his appearances in the FA Cup (three times with Stoke).
I'll pass that on Michael.

Former England captain on BBC One
Liverpool have a very big squad and when you rotate like Jurgen Klopp did you are gambling. He is looking to guys who aren't in the first team to give him a performance and they failed miserably.
Wolves boss Nuno Espirito Santo to BBC Sport: "I am very pleased, the team performed very well in a tough game. We took our chances.
"Ruben Neves has talent, he has done it before and we encourage him to shoot from range. It was a good strike and the fans were very special.
"The draw is the draw, next we have Manchester City so we are focused on that."
Here's how Wolves earned a trip to either Shrewsbury or Stoke.
I've a sneaking feeling that Arsenal v Manchester Unitd may be on TV.
