( CNN ) -- Lionel Messi is not for sale . That was the defiant message from Barcelona 's new president , who is adamant that the club 's all-time leading goalscorer is going nowhere amid reports French club Paris St Germain want to sign the Argentine . Josep Maria Bartomeu will sit down with the four-time World Player of the Year to thrash out a new contract which will see him remain as most highly-paid at the Camp Nou . `` We want to sit down , without any rush , with Leo 's father -- it 's not something that 's happening tomorrow , we have plenty of time , but we will do what we have to to ensure he 's the best paid player , '' said Josep Maria Bartomeu , who assumed control at Barca after Sandro Rosell 's resignation last week . Messi arrived at Barca in 2000 , graduating through the club 's youth system before going on to establish himself as the best player on the planet . Since making his first team debut in 2004 , Messi has helped the team win six Spanish league titles , two Spanish Cups and three European Champions League crowns . Blog : Is Ronaldo really the best ? The club 's determination to keep hold of Messi will be sweet relief to Barca fans after a turbulent few weeks . Former president Rosell stepped down after a Spanish judge 's decision to investigate the deal which saw Neymar move to Catalonia from Brazilian team Santos last June . The club initially announced the deal was worth $ 78 million , but the breakdown of the agreement was never revealed . A Barcelona member launched a case against Rosell for not disclosing the full details and the club was asked by Spanish authorities to hand over documentation , as well as accounts for the past three years . Bartomeu , who will continue as president until the end of the current term , which finishes in 2016 , explained that he spoke with senior players at the club before discussing details of Neymar 's contract at a previous press conference . `` I explained to the captains that we would be showing details of Neymar 's contract , '' said the former vice president . `` We have to be grateful to Neymar that he came here , when he could have earned more money at other clubs .
