Fernando Alonso has indicated to McLaren-Honda that the struggling Formula One team need to be winning races within the next three months if he is to stay on.
Alonso: "If we are winning..."
Speaking ahead of this weekend's Canadian Grand Prix, Alonso - whose contract expires after the 2017 season - declared: "We have to win. If we are winning, before September or something like that, I will make a decision and I will stay."
Alonso: Brown comments on Honda "what you expect"
With McLaren bottom of the 2017 standings and yet to score a point, executive director Zak Brown told Reuters on Wednesday that the team have "serious concerns" about their title-winning potential with current engine provider Honda.
The British outfit are "near our limit", Brown added.
Asked about Brown's remarks, Alonso said: "Zak's comments are probably what you expect for Zak to say. He wants to win, he wants to put McLaren again in a contender position for the championship.
"After three years we are not in that position," concluded the two-time world champion, who missed the F1 calendar's most recent event, the Monaco GP, to take part in the Indianapolis 500.
