Now that kind of performance is what this Everton team is capable of. With fantastic, quick, exciting football and plenty of goals, this was the closest we've seen to Martinez's first season in a while.
There were literally no weak points to this display. Starting at the back, both John Stones and Phil Jagielka were absolutely rock solid throughout the game and dealt with the threat of Graziano Pelle superbly, while Seamus Coleman and Brendan Galloway were also excellent.
This display though, will be remembered for the performances of both Romelu Lukaku and Ross Barkley. These two are often cited as the future of Everton and today was a clear indication why. Lukaku's goals were both wonderfully taken, while Barkley's wasn't bad either.
We've said many times that Lukaku and Everton need to start playing to his strengths and today they did that, with the Belgian running at defenders constantly and scaring them throughout, leaving St Mary's with two goals and three points as a consequence.
Let's give some credit to Arouna Koné as well. He was asked to do a thankless task of tracking back in this game and did it superbly, but going forward he was also a threat. His assist for Lukaku's first was nothing short of brilliant. He's looking on fire after a pretty drab pre-season, it's strange what a goal can do for your confidence.
Overall, this was probably one of the best displays we've seen under Martinez, with counter attacking football coupled with a resolute defensive display. Interestingly, it came about from us playing less football and being more direct.
Has the Catalan finally learned his lesson? That remains to be seen, but for now, a fine first win of the season for Everton should have us all happy.
