The Reds' manager Jurgen Klopp suggested he will try to ease the Brazilian midfielder into action, which probably means that Coutinho will start on the bench at Southampton.
“I think Phil [Coutinho] is fit enough to be part of the squad and that means there could be minutes, but it depends on the game,” said Klopp.
“It was six or seven weeks ago and that is long, so he needs minutes in training especially, but then as soon as possible minutes in games.
“No final decision has been made until now but tomorrow would be his fourth session with the team.
"It is not that many but for being in the squad it is enough.”
