World champion Lando Norris said Thursday that McLaren have made some progress since a disappointing opening to the season in Australia but warned they still need to "improve in all areas". 

Pre-season favourite George Russell led home a Mercedes one-two in Melbourne, ahead of both Ferraris, with Britain's Norris fifth -- 51 seconds behind the race winner. All weekend Norris had railed against the latest version of F1 cars, which have a 50-50 split between conventional and electrical power, saying they were "probably the worst" the sport had produced.
