His current terms are, however, only due to run until the summer of 2021 and no extension has been agreed as yet.
Messi will be free to speak with his many suitors from January, with Barca’s next round of presidential elections not due to take place until the 24th of that month.

The likes of Manchester City and Paris Saint-Germain are said to be already jostling for position at the front of a recruitment queue, with a remarkable agreement potentially in the offing.
Tusquets believes Barca should have avoided any threat of Messi walking away for nothing by bowing to his demands in the last window and sanctioning a big-money sale.
He has told RAC1: “Economically speaking, I would have sold Messi in the summer.
