BARCELONA: Double world champion Fernando Alonso said he was “exhausted” having to explain Aston Martin’s poor performance after a new low in front of his home Spanish fans. Alonso starts Sunday’s Barcelona-Catalunya Grand Prix in last place, the 44-year-old outqualified for the first time in 42 races by Canadian teammate Lance Stroll. Stroll, son of team owner Lawrence, qualified 21st and with a best lap more than four seconds slower than George Russell on pole position for Mercedes. “We knew we have the worst car and the worst engine and we’ve been very clear in every race so far that we have to work,” Alonso said at the Circuit de Catalunya. “We repeat the same thing and it’s exhausting. We’re last, we know it, and we have no problem admitting it,” he told Spanish media. “We have the worst engine, very poor energy deployment, gearbox problems and aerodynamic problems.
