The former Udinese star has hailed the influence of the club's former coach following his fine start to the 2013-14 season
The Chile international was heavily linked with a move away from Barcelona this summer after he struggled to find his best form last term, but he eventually opted against a transfer as the club's former head coach told him that he still had a role to play at the Catalans.
"Tito has played a big role in my career," Alexis told Sport.
"I had a difficult year, but he always supported me and told me not to leave.
"He insisted that I should stay at Barcelona and ignore everything that was being said about me in the press."
The 24-year-old Alexis has been in fine form for the Blaugrana this term, netting four goals in six La Liga appearances, while setting up three more.
