It would be a bizarre turn of events if Morata did return to Italy. He joined Juve originally from Real in 2014 before the Spanish club triggered a €30 million buy-back clause in his contract to return to Spain last summer.
A return back to Italy would not be totally out of the question as the Italian side tried hard to keep him last summer, but a switch to the Premier League would perhaps be more likely due to the transfer fee the striker would command.
Arsenal have been consistently associated with a move for Morata, even in recent weeks, but it likely any interest would depend on the future of Alexis Sanchez. Talks over a new deal for the Chilean are believed to be still ongoing but there appears to have been no breakthrough yet.
