Juventus striker Mario Mandzukic is not training with his team-mates due to an agreement he has with the club, says head coach Maurizio Sarri.
Speaking ahead of Juventus' Serie A match against Bologna on Saturday, Sarri said: "In this moment Mario Mandzukic is not training with the group due to an agreement he has with the club."
Mandzukic, who is a target for Manchester United in the January transfer window, attends Juventus' training centre but works apart from the first-team squad.
Sky in Italy say Mandzukic, 33, who is yet to make an appearance for the Italian giants this season, will be available for transfer in January.
United made a late move for the Croatia international at the end of the summer transfer window, after a move for his team-mate Paulo Dybala collapsed, but ended their pursuit on Deadline Day.
Ole Gunnar Solskjaer, the United manager, has this week told Sky Sports pundit - and former team-mate - Gary Neville that he is "sure" the club will bring in new a signing in January "at the right price".
And speaking last month, Solskjaer made clear bringing in a striker was a priority after United's failure to replace Romelu Lukaku and Alexis Sanchez.
"You don't have to be a rocket scientist to know it's a forward we're going to try to recruit next time," Solskjaer said. "We're looking for some creativity and goals, but they [potential signings] have to be the right one.
"There were strikers available [in the summer] but not the ones we wanted. We couldn't get the one we wanted."
United are considering a move for former Liverpool midfielder Emre Can in January, Sky Sports News understands.
The 25-year-old Germany midfielder spent four seasons at Anfield before leaving on a free to join Italian club Juventus at the end of the 2017/18 campaign.
It is understood Juventus would want in the region of £35m for Can, who is yet to start under Sarri this season.
Can, like Mandzukic, was omitted from Juventus' Champions League squad - despite receiving assurances he would be included.
"The fact that I am not in the Champions League squad is extremely shocking for me, mainly because I was promised something different last week," Can said in September.
"I had talks with other clubs [in the summer] and one of the conditions for me to stay was to be part of the Champions League squad. Then they phoned me and told me, in a conversation that didn't even last a minute, that I was not on the list and they didn't give an explanation.
"That makes me angry and furious, they haven't been honest with me. If I knew about it earlier, I would not have stayed at Juventus."
