Price, who is a reliable source of German football news, understands Keita has been playing up at Leipzig in a bid to get sold to Liverpool.
The club themselves are determined to resist any approach from Liverpool to move the midfielder earlier than scheduled.
The Reds have an agreement in place for the Guinea international to join them in July but they now want him in January following the £142million sale of Philippe Coutinho.
Leipzig play Schalke today at home and it could be Keita’s final chance to say goodbye to the fans.
Price told Express Sport: “Leipzig face Schalke in the clash of the weekend in the Bundesliga. Win and they potentially go second, lose and there will be a five-point gap.
“But it will be important for more than just the league table.
“Leipzig don’t play at home for another two weeks after this one and it’s likely what happens here could be a big indicator of Keita’s mindset.
“We saw Coutinho wave to all corners of Anfield days before he was sold to Barcelona and Keita could do the same.
“While the last few weeks have been difficult, it’s a club he holds in high regard and he wants to go out in good grace. He doesn’t want to be remembered with any bad feelings.”
Boss Ralph Hasenhuttl has tried to dismiss the chances of a departure and said: “The situation hasn’t changed
“We have always said that there’s no reason to let Keita leave early and that’s the way it will be.
“Keita will play against Schalke this weekend and hopefully he’ll play well. That’s the only thing I’m interested in.”
And now a picture of Keita holding the Liverpool shirt with the number 8 on has emerged online.
It is grainy and could well be a fake but it is another talking point in the on-going saga.
Yesterday Keita registered a company in the UK amid claims the deal would be complete by Sunday and he would wave goodbye to Leipzig fans this weekend.
A company under the name ‘NK8 LIMITED’ has been registered on the Companies House website. Two people are listed as officers – Naby Deco Keita and Bjorn Alexander Bezemer.
Bundesliga journalist Chris Williams then tweeted: “Information from within Leipzig this evening that Naby Keita will become a Liverpool player on Sunday.”
