Liverpool boss Brendan Rodgers insists Luis Suarez must apologise to the club and his team-mates before he can return to training with the rest of the squad.
The Uruguay international has been made to train on his own as the Reds boss was unhappy with the attitude he has shown recently, which culminated with interviews earlier this week in which he claimed the club had reneged on a deal to allow him to leave this summer.
That upset Rodgers and he has isolated the 26-year-old, who owner John Henry has said will not be sold to Arsenal despite the Gunners' bid of £40,000,001.
Suarez is suspended for the first six matches of the season as his ban for biting Chelsea's Branislav Ivanovic is carried over, but even if he does not leave in the current transfer window there are still bridges to be repaired.
"Initially there will be a recognition that [there needs to be] an apology to his team-mates and the club," said Rodgers when asked what Suarez needed to do next.
"I have seen him over a period of time I know it is not the Luis Suarez we know and I have to protect the fans and the players because they deserve more than that.
"He has spent some days working on his own. The group has been separate to that and working very hard.
"When he is back from his international trip [Suarez will travel to Japan with Uruguay in midweek] we will assess it from there.
"I spoke to John [Henry] when we were in Norway during the week and we are all on the same page really. We are adamant that he will not be going to Arsenal - that is for sure. We want to keep him.
"Luis missed a few games at the end of last season and we continued to score and win without him. That is not to say that we don't want him here. He is a world class striker and when he is committed to the cause of playing for Liverpool then we will welcome him back with open arms."
Speaking on Friday, Arsene Wenger confirmed Arsenal will respect Liverpool's decision if they choose not to sell Suarez.
Wenger said: "There is nothing to add to what I said already about the transfer of Suarez.
"If it will be done, it will be done in a respectful and amicable way with Liverpool.
"I didn't read (Henry's) statements but we'll be faithful to the way we want to behave.
"To make a transfer happen, you need the agreement of three parties - the buyer, the seller and the player.
"We know what we want to do. The player, if I look at the statements, (does) as well. Liverpool at the moment do not agree. If they change their minds or not, I don't know. We'll respect that."
Former Liverpool manager Graeme Souness, meanwhile, told Sky Sports News that Suarez should show Liverpool "loyalty" and remain at Anfield for at least another season.
"I think he does [owe Liverpool] and everyone in their correct mind would see it like that," said Souness, who won three European Cup titles as a player with Liverpool.
"I think back to the T-shirts at Wigan when he got himself in real bother and the Ivanovic situation last season - the board have stood by him, the club have stood by him and the manager has stood by him.
"You would like to think a bit of common sense and loyalty would prevail but that doesn't appear to be the case.
Sky Bet have now made Suarez odds-on to stay at Liverpool for the first time since the striker indicated his desire to leave the club.
Sky Bet's Chris Spicer said: "It's one of the most surprising shifts we've had this summer as we've been sure Suarez would force a move ever since he hinted at wanting a move back in May, with the odds on him staying being as long as 3/1."
