Lionel Messi and Barcelona are discussing terms on a new contract.

Messi is under contract until 2018 but Barcelona would like to extend his deal.

"Messi has two years of contract but we will talk with him to renew because we want him to continue," Josep Maria Bartomeu told Catalunya Radio.

Bartomeu added: "Messi is the number one player in the world.

"The tax issues faced by his family is something that we do not like because sometimes players are not responsible for these things.

"We talk to all players and in the case of Leo, he is a very strong person, with great ambition, and has returned better than ever, demonstrating the desire to continue making people happy in Barcelona. We can always count on him."
