Joan Laporta warns Messi will leave if he is not elected.
Laporta is the favourite to win the presidential election when the elections will be held on Sunday.
Last summer, Messi was destined to leave Camp Nou but chose to stay for another season instead.
The six-time Ballon d’Or winner has entered the final few months of his contract and Laporta promised he would do everything to persuade Messi from not leaving Camp Nou in the summer.
‘I have a great relationship with Leo [Messi] and he will consider whatever proposal I make,’ Laporta said during a TV debate on Catalonian channel RAC1 on Tuesday with rivals Toni Freixa and Victor Font.
‘If I don’t win, I am sure that Leo will not stay at Barcelona.
‘Messi will weigh up the offer we make him. I’m convinced that if the other candidates win, Messi will not remain at Barcelona. He wasn’t happy during Freixa’s time on the board.’
‘He’s not guided just by money,’ Laporta added. ‘He wants a competitive team to win.
‘I’m sure he’ll listen to my offer, just as I am [sure] that if someone else wins he will leave.’
