The Reds made 16 with the win over Sheffield United on Saturday, two shy of City's record of 18.
Asked about the possibility of winning 18 straight games, he said: "(There are) interesting games coming up. It doesn't sound too likely. But we will try and first and foremost Salzburg and then Leicester.
"Then it is the international break and hopefully everybody comes back healthy. That is most important.
Sadio Mane and Mohamed Salah will play against each other in Singapore, very interesting game obviously, it's not qualification for anything. So hopefully everyone comes back healthy and then we try to prepare for Man United."
He added: "I try to understand how other people think about things but from the way I think about things I'm not interested in the number to be honest. It's just a number.
"So, you only can create a streak like this if you're always in the next job. The next job is Salzburg which is a different competition and then Leicester City and that will be difficult."
