We travel to the home of the FA Cup holders who, since capturing the trophy in Cardiff, have added speedy striker Craig Bellamy to their ranks.
JJ spent three years at Newcastle United with the Welsh international forward and recalled some wise words from the former Norwich and Coventry player on his own introduction to the St James Park side.
"He is a major threat," said the scorer of two goals already this season. "I used to play with him from midfield and he was a delight to play alongside. In one of my first games he told me if I was ever in trouble just to stick the ball down the channel and he would chase it.
"Most of the time he got there as well because he is that quick. He will be in opposition in this game and I will be warning Leds and Daws about him, but they know him themselves as he is a top player.
"He is a danger we will have to look out for. He is always up for the games, constantly talking, shouting and getting his point across.
"Craig is good to have in your team, but we have players who can do exactly the same thing. Come the day I'll say hello, but there will be no friends during the game."
Meanwhile, JJ said the team are excited by the prospect of the trip to Anfield, from where they are hoping to click into gear after a relatively slow start to the season.
"They are a top side and, if we go there and get a good result, we will definitely be able to go on from it. We are looking forward to it and it is always an interesting place to go, Anfield.
"It is never easy, but if you look at last season we could have nicked a win there as we had a few chances in the second half and a lot of possession. We know our capabilities and we're going there to try and win the game."
Jermaine Jenas is well positioned to identify the threat likely to be posed by a recent Liverpool recruit on Saturday.
