Tevez's agent Kia Joorabchian has issued High Court proceedings against West Ham in a bid to resolve the thorny issue of the player's ownership.
"I have not been involved in this and it is not Manchester United's decision," Gill said.
"Clearly, it is a dispute between Tevez, the owners and West Ham.
"Hopefully, that can be solved relatively quickly and he can come to join us. I would have thought they have taken this decision in the belief that he can join us."
