Arsenal fans are certain Shkodran Mustafi has fired a sly shot at Alexis Sanchez.
The Chilean completed his move to Manchester United on Monday in a deal which has seen Henrikh Mkhitaryan move to the Emirates.
Sanchez, who will wear the No 7 shirt at Old Trafford has signed a four-and-a-half year deal worth £14 million a year after tax.
Much of the 29 year-old’s final months at Arsenal appeared to be full of rift and squad division in the side.
These rumours have only been further escalated by Mustafi’s tweet.
The Germany international posted a photo of him in training with the caption: ‘Come on Gunners, all together now!’
Henrikh Mkhitaryan also took part in the training session, but will not be available for Arsenal’s Carabao Cup second-leg with Chelsea.
Arsenal fans have seemingly read between the lines and deciphered the hidden message behind the Mustafi’s tweet.
Take a look at what they had to say on Twitter…
