Fernando Alonso has called on McLaren to retain his team-mate, Jenson Button, for the 2016 season.
Button recently said that he hopes to resolve his future with McLaren "over the next few weeks", but it is understood that McLaren are considering giving his seat to Stoffel Vandoorne or Kevin Magnussen, who are both members of McLaren's young driver academy.
However, Alonso believes that it would be a mistake to let Button go with the Briton an experienced driver who knows how to win.
"Jenson has been quite good all season," Alonso told reporters. "We've been working together very closely to help the team.
"The experience Jenson has, it been very, very important for the upgrades we have brought to the car, in terms of the power unit and aerodynamics. So if Jenson stays I think it's a good thing for the team."
Alonso is hopeful that a decision will be made sooner rather than later, and conceded that he was unsure of how he would work with a new team-mate.
"If they decide they need to change something there will be some advantages and some disadvantages for the team, I guess," he said. "The only thing I can say, the only thing I know for sure is working with Jenson has been very, very productive for the team and for myself, learning a lot of things.
"Working with the other guys, I cannot tell much. But they will make the decision they think is the best for the team and hopefully they do it before Christmas time."
