Henrikh Mkhitaryan, Chris Smalling, Ander Herrera and Marcus Rashford were among the smiling faces pictured in the snap as United gear up for their return to Premier League action against Stoke on Monday night.
Though, the player is struggling to get back in full flow this season and looks to have been sidelined in recent weeks.
The manager has now set his sights on wantaway Arsenal forward Alexis Sanchez, whose move to Manchester City has reportedly boiled off due to the Citizens' disinclination to meet Arsenal's asking price.
The former Borussia Dortmund attacker has endured an inconsistent time of things during his 18 months at Old Trafford.
The Armenian started this season in a similar vein, laying on regular assists for the likes of Romelu Lukaku and Paul Pogba, before a loss of form led to another ostracizing by Mourinho.
"My approach to players is that every player has a price", Mourinho said when asked directly about whether Mkhitaryan would stay, as quoted by Sky Sports. Still, if the right player comes along, and at a steal of a price, you have to pull the trigger on executing the transfer buy. I am not the kind of blind manager - blind in the sense that, this player is untouchable, he can never be sold.
Man United now favourites to sign Sanchez after City pull out
During last year's pre-season transfer window, Sanchez and Arsenal almost agreed on a £60 million (AU$103 million) contract. French side Paris St-Germain have also been linked with Chile forward but Sanchez's preference is to join Manchester City .
United did not buy a single player in the 2016 or 2017 winter transfer windows, and the only player they picked up in the 2015 January market was back-up goalkeeper Victor Valdes.
"He consulted a Doctor and we made the decision to stop".
"But Mkhitaryan played the last match in the FA Cup against Derby".
Ibrahimovic suffered a double knee ligament blow in the UEFA Europa League against Belgian side Anderlecht at Old Trafford in April of previous year.
Elsewhere, Ashley Young is still serving his three-match suspension while Eric Bailly is working his way back from an ankle injury so both players are certain to miss the Stoke game.
"He is our player, he is a very good player, so he trains, he is selected and Monday he plays", Mourinho told the Sunday newspapers.
