Following a series of disappointing results for the Blaugrana, and reported dressing room unrest between the squad and head coach Quique Setien, rumours have started circling that Messi may finally be ready to move on.
During the draw against Celta, Messi was apparently seen ignoring the instructions of assistant coach Eder Sarabia.
It is this run of form and the prospect of surrendering the title to Madrid which has left Messi disillusioned, according to Cadena SER.
For Madrid head coach, Zidane, though, he hopes that Messi remains with Barca.
Zidane said: "I don't know what will happen but we hope not because he is in this league and we want the best in this league,.
