Lando Norris has expressed his frustration at McLaren's Mexico City Grand Prix performance despite his charge through the field to fifth - asking "Why would I ever be happy about a day like this?"
The British driver showed promising form in practice, ending the final session just behind pace-setter Max Verstappen with a potential front-row on the cards, but a mistake, ill-timed yellow flag and fuel system problem knocked Norris out in Q1 - as he started 17th following penalties to others.
In the race, he started on Softs before an early pit-stop to fall back into clean air on the Hards, climbing to 10th by the red flag on Lap 34.
A poor launch from the second start dropped him down five places, but armed with Medium tyres, Norris carved through the field, barging past Daniel Ricciardo and George Russell on his way to fifth.
The result ended Norris's run of four straight podiums, and left a sour taste in his mouth - with the gap to Carlos Sainz and Fernando Alonso for fourth in the Drivers' 14 points.

Norris: Why would I be happy with a day like this?
"People complain and say 'Why am I so disappointed all the time?'," Norris explained to media, including RacingNews365.
"It's because of days like this race. Of course, I'm going to be disappointed.
"There's a chance to finish on the podium, get another trophy, and score more points. Why would I ever be happy about a day like this?
"We put a lot of focus on today, that was evident and paid off, but I'm never going to be happy after a day like [Saturday] right?
"Because I know what we're capable of doing.
"Whenever you have a day like today, you think what could have been? There's too many 'what could have been at the minute' so I just need to tidy some things up and things can start to roll.
"It will be the same for anyone in my position - maybe some people are better [at dealing with it] than others, but you are never going to be happy when you've messed up and let the team down. There are 700, 800 people people that are relying on me to do a good job.
"So when you don't, how can I put a smile on my face?"
