Keita sustained a hip injury ahead of Liverpool’s UEFA Super Cup clash with Chelsea in Istanbul last month, but will rejoin his teammates in today’s session.
Elsewhere, Klopp reported both Alisson and Origi have take steps forward in their recoveries from respective calf and ankle issues.
The manager told his pre-Chelsea press conference: “Naby Keita is back in training at least, with the team. Today for the first time with the team.
“Ali is making big progress, but is still away. He had a proper session yesterday with John Achterberg, but is not in team training yet.
