The Chilean is expected to extend his existing contract for two more years and is set to earn around 5 million euros annually with the Italian champion.
The 26-year-old Vidal is expected to extend his existing contract, which expires in 2016, for two more years, with him set to earn around 5 million euros a year. Vidal has emerged as a rising star at the club since joinng from Bayer Leverkusen in 2011 and has caught the eye with some impressive performances both in Serie A and the Champions League.
"Vidal arrived in Turin and the move was met with some scepticism, but he has done very well and now he should be rewarded," Marotta told Tuttosport. "There have been big clubs in Europe interested in him, but in the coming weeks, his contract will be prolonged and economically adequate."
Meanwhile, ahead of the Bianconeri's clash with Inter in next Saturday's Derby d'Italia, Marotta believes the Nerazzurri can be title contenders and threaten Juventus' reign atop Serie A.
"It will be a tough match for us, it will be important to determine our quality but also the quality of our opponents, who I think can compete for Scudetto," Marotta said. "I would be happy if we lose this and break our 'days at the top of the table' record if at the end of the season we will win the Scudetto. And I would be even happier if we beat Inter and win the Scudetto as well."
