McLaren have been beaten by a shock rival in first practice at the Saudi Arabian Grand Prix, with Max Verstappen's Red Bull struggles also continuing in Jeddah.
Whilst McLaren ended the session with Lando Norris in P2 and last weekend's Bahrain Grand Prix winner Oscar Piastri in fourth, split by Ferrari's Charles Leclerc, it was Alpine's Pierre Gasly who topped the timings in FP1.
Gasly set a lap time of 1:29:239 around the Jeddah Corniche Circuit, edging Norris by just 0.007 of a second as he backs up his strong showing in Bahrain last time out.
Elsewhere, as mentioned, reigning world champion Verstappen continued to struggle with instability in his RB21, only able to set a time quick enough for P9 in the session, with Lewis Hamilton one place ahead in P8 and team-mate Yuki Tsunoda one place behind in P10.
With that said, let's take a look at the results and times in full from FP1 and how the order is looking ahead of FP2 later in the day.
