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?
