Lewis Hamilton will start the Monaco GP from seventh place, after a subdued qualifying session from the Mercedes driver.
Hamilton never looked a threat for the pole position in Monte Carlo, eventually winding up in seventh place and some three quarters of a second away from the front.
Any chance of a late improvement were scuppered by the red flags for Leclerc's crash, and the British driver was left very disappointed by his qualifying showing.
"It's almost impossible to overtake," Hamilton told Sky Sports F1.
"Almost impossible where we are is pretty much the case, when everyone's in the same speed.
"So, qualifying is Saturday and, you know, Saturday is the day so that really does put, for sure, the win out of reach, but I guess the minimum will be hopefully seventh and then we've got to try to figure out how to go forwards."
"It didn't feel too bad on Thursday, and we made some changes and it was pretty terrible today so we've got to go back to the drawing board
"I just had such a lack of grip out there, which then leads you to try to overdrive and start pushing to get more from it but, to no end, it just doesn't improve. So, yeah, difficult one. Valtteri was able to get something out of it but I think we've definitely had some problems."
