Liverpool target Naby Kieta is alleged to have been involved in a training ground bust-up, after going in with a strong challenge on his Leipzig team-mate Diego Demme on Monday.
Reports in Germany state the pair had a coming together during a morning session, which culminated in players having to be separated and the training session brought to a premature end by coach Ralph Hasenhüttl.
Keita went in high on Demme during a practice match, leaving his team-mate doubled over in pain and clutching his knee, as reported by German publication Kicker.
The Guinean midfielder is a primary target for Liverpool this summer, who have already had a series of bids rejected by the Bundesliga side.
