Veiga spent the second half of last season on loan with Juventus and scored against the team in Villarreal's recent Champions League draw.
He scored in the 90th minute to earn a draw against his former team, and Montalbano said Veiga was happy with his performance, praising his "incredibly intense, high-level performance."
Montalbano also mentioned that Veiga was happy to have scored, as he often tries to create opportunities from set pieces.
The agent added that Veiga had a strong and intense relationship with Juventus during his time there, and that the club's fans saw his dedication to his work last year.
Regarding Veiga's decision not to return to Juventus this season, Montalbano explained that it was due to exceptional circumstances, including the timing of the Club World Cup and changes in management at the club.
The agent said negotiations for Veiga's loan were complicated due to the uncertainty surrounding Chelsea's future and the need for Villarreal to evaluate their situation for the upcoming season.
The change in management at Juventus also created challenges, as the new management team needed time to assess the situation.
