Milan had tried to sign Tevez in January last year after his bust-up with Roberto Mancini, but they settled their differences and the Argentine returned to first-team football later that season.
The 29-year has been linked with a move to Italian champions Juventus but Galliani is hoping that Tevez opts against the switch.
"I would mind a bit if he should go to Juventus, given the friendship we have built with him," he told Sport Mediaset.
"But the president Berlusconi is right - if Tevez had arrived in Milan, Balotelli would not have come here.
"We also followed Neymar but he was too expensive for us."
Reports in Italy have suggested that Juventus are also chasing the signing of Real Madrid striker Gonzalo Higuain, but say that they will only sign one of the two Argentinians.
