Despite Leipzig seemingly holding out for a huge sum, Keita looks likely to be on his way out of the club before the window closes.
Liverpool looked to be at the front of the queue to land the Guinea international, but he may have cast doubt on any deal after admitting that he hopes to one day play for a side such as rivals Manchester City.
"I love Leipzig, and I will never forget this city," he told Die Welt. "I hope that I am at the level in two, three years that I could play for one of the very big clubs. This includes Barcelona, but it also includes Real Madrid or Manchester City."
Keita also revealed that Arsenal and Southampton previously made an approach to sign him, prior to joining Leipzig from Red Bull Salzburg last year.
