McLaren chairman Ron Dennis says he would have no problem if Fernando Alonso rejoined the Formula 1 team.
The two men fell out dramatically when Alonso raced for McLaren in 2007.
But asked if he would object to the Spaniard returning, Dennis said: "One has to recognise the first objective of any grand prix team is to win races.
"Whatever obstacles sit between a team wanting to win and winning, be it engineering, fiscal or human issues, you resolve them. You never say never."
McLaren team principal Martin Whitmarsh initially tried to sign the double world champion for 2014 following tensions between Alonso and Ferrari this season, but has now switched his attentions to getting him for 2015.
A fortnight ago, Whitmarsh attended the opening of an exhibition in Madrid that showcases artefacts from Alonso's racing career.
Officially, Whitmarsh went as one of Alonso's former F1 team bosses, even though, strictly speaking, Dennis ran McLaren at the time the Spaniard was with the team.
But sources close to McLaren say Whitmarsh also took a contract for Alonso to assess.
Alonso's manager, Luis Garcia Abad, dismissed notions that a contract had already been agreed between the driver and McLaren as "Formula 1 fiction".
"You cannot have two signed contracts, as when you sign one, you must notify the body that controls it," Abad said. "So it is technically impossible."
He added that "an unsigned agreement is not an agreement".
