By Alan Baldwin MEXICO CITY (Reuters) -McLaren boss Andrea Stella says Formula One title contenders Lando Norris and Oscar Piastri can both feel confident going into the last four races, with neither likely to have a track advantage.

Oscar Piastri admitted he was dumbfounded at his lack of pace after another difficult qualifying session for the F1 championship leader. Piastri, who has a 14-point lead over McLaren teammate Lando Norris and 40 points ahead of Red Bull’s Max Verstappen, has endured a poor run of form and Saturday at the Mexico GP was no different.

Lando Norris won his fifth pole of the season while Oscar Piastri was a distant seventh in Saturday qualifying.

Oscar Piastri's lead in the Formula 1 championship is shrinking after a tough weekend in Texas. At the United States Grand Prix, his teammate Lando Norris and Red Bull's Max Verstappen gained ground.
