Reports in Spain suggest that Alvaro Morata's return to Real Madrid last year has not gone at all as he had hoped, and that the Spain international wants to leave the Bernabeu next summer unless something big changes between now and then.
Well-connected Spanish radio show El Larguero claimed on Thursday night Morata was promised significant playing time after his €30 million move back from Juventus and now feels "tricked" by coach Zinedine Zidane. Despite scoring a goal every 126 minutes on the pitch in all competitions this season, he remains firmly behind Karim Benzema in the pecking order, while Cristiano Ronaldo's conversion into a number nine has also limited his chances of starting regularly.
All of which means that Morata could be on the move again once the transfer window opens, even though his current Madrid contract runs until 2021. If so, it is unlikely that the 24-year-old, who has eight goals in 16 senior caps for Spain, would be short of potential suitors.
But who might be the most likely?
Morata's two seasons with Juventus saw him score 27 goals and make 19 assists in 93 games across all competitions while also winning two Serie A titles, two Coppa Italia trophies and reaching a Champions League final.
Even last summer when it was clear he was about to go back to Madrid, Morata was always very careful to speak highly of Juventus and its fans, stressing how much he enjoyed his time in Italy. That spell abroad also saw the youngster meet an Italian woman who is now his fiancee, further keeping the connection with the country alive.
The biggest obstacle to a move back would be Gonzalo Higuain; Juve spent big to sign the 29-year-old centre-forward last summer. Making a deal more likely could be Madrid's long-reported interest in the biancorosso's other Argentina international, Paulo Dybala: some kind of part-exchange might end up suiting all sides.
The Juventus manager when Morata joined back in 2014 was Antonio Conte, although they were not long together, as Conte soon left to take over as Italy national manager. Conte has apparently remained a firm admirer of his one-time charge, and there has been regular speculation that he wants a chance to work together over a longer period.
Chelsea, of course, already have another Spanish centre-forward in Diego Costa, but his future at Stamford Bridge remains up in the air following the very public recent disagreement with his bosses amid big-money interest from China.
Madrid's need to sign a goalkeeper next summer and long-running interest in Blues stopper Thibaut Courtois could also help to make a deal more likely.
3. Borussia Dortmund
Borussia Dortmund are reportedly long-term suitors of Morata, having tried to get him to join them before he moved to Juventus, and they again made their interest known last summer but were unable to match the financial and emotional allure of his hometown club Madrid.
Morata's mobility and work rate would make him a decent fit at the Westfalenstadion, where other raw but talented strikers such as Robert Lewandowski and Pierre-Emerick Aubameyang were given the right environment to develop into world-class stars.
Even if Aubameyang is sold next summer, Dortmund are unlikely to offer the riches available elsewhere, but in pure footballing terms, this could be the best fit.
Another team who have often been mentioned in speculation regarding Morata over recent years are Arsenal, as their seemingly endless search for a top-class centre-forward drags on.
Most Gunners fans and pundits would see Morata as a significant upgrade on their current traditional number nine, Olivier Giroud, and would be pretty excited about the idea of him linking with Alexis Sanchez and Mesut Ozil in an attack of former La Liga stars.
Morata has the technical ability to link up with Sanchez and his former Madrid teammate Ozil while also providing a physical presence and nose for goal that could, maybe, possibly help Arsene Wenger's side finally end their long wait for a Premier League title.
5. Paris Saint-Germain
Although Edinson Cavani has been filling in nicely up front for PSG since Zlatan Ibrahimovic left last summer, there is still a widespread feeling that the serial Ligue 1 winners need to sign a more reliable centre-forward if they are to really challenge in the Champions League.
Morata has shown a big-game mentality by scoring in both the UCL semifinal and final during his first season at Juve, and he also netted the winner against current PSG coach Unai Emery's then-Sevilla side in the group stages of the competition last season.
Assuming their disastrous €30m deal for Jese Rodriguez last summer has not put the Parisians' backers off of signing former Blancos starlets forever, this move could make a lot of sense for both the player and club.
