The 27-year-old is out of contract at the end of the season, and suffered an injury before Jurgen Klopp’s side were defeated 2-1 by Manchester United at Old Trafford.
According to Goal, there is a worry that he’ll be sidelined for a while alongside Thiago Alcantara, Curtis Jones and Alex Oxlade-Chamberlain, but this isn’t likely to stop any potential suitors from the Bundesliga.
Keita came to the limelight when performing exceptionally well in the German top flight with RB Leipzig, who are also in the running to bring him back to the club.
He left Die Roten Bullen for Anfield in 2018 for an initial £48m aged 23, tasked with leading Liverpool’s midfield for the half-decade ahead.
It hasn't worked out that way.
Injuries and other spells out of the side has seen Keita play only 76 times for Liverpool in the Premier League across four years, missing 50% of matches, whilst only featuring 117 times overall.
Last season was his most productive appearance wise though, with the arrival of Dr Andreas Schlumberger as head of recovery. He played 40 times, including ten of 12 matches in the UEFA Champions League.
With Dortmund interested, it may lead a keen mind to think about the potential ramifications of a deal for Jude Bellingham, which has been rumoured for the last few years.
The Englishman is almost like-for-like in style, more robust and has youth on his side, so a swap deal with cash on top could be viable. However, these deals are extremely complicated.
It would be unlikely that he is let go this window, but next summer, Liverpool’s fourth most expensive signing could be leaving on a free.
