The Black Cats secured their Premier League survival in convincing fashion, Lamine Kone hitting a brace and Patrick van Aanholt converting a free-kick as the Wearside club romped to a 3-0 win.
The result relegated Norwich and Newcastle, but the real worry should be with Everton, as they failed to seriously pose a threat against a team who has spent the majority of the season in the bottom three.
Martinez’s team displayed their usual frailties, looking defensively weak and susceptible to conceding the lightest of goals.
However, at the Stadium of Light, the Toffees failed to even show their strengths, lacking any real attacking threat and failing to control possession with their usual imposing style.
It was a game which is sure to have increased pressure on Martinez’s job, but the Spaniard actually believes his team were doing everything right in the game.
When asked whether he was impressed with the performance, given the shocking display against Leicester at the weekend, the Spaniard said: “It was a completely different type of performance.
“The desire was there, the work rate was there and the intent was there.
“From a purely technical aspect, I think our possession should have ended up with a better threat in the final third in the first-half. In the second-half we had more of a threat.”
If there is anything to ease the pressure on Martinez, it will be the excuse that injuries have ravaged his squad this season.
For much of the campaign he has had to call upon youth players to fill in his defence, a fact which has not gone unnoticed by the 42-year-old.
“We had a lot of injuries, and it is good to have some senior faces back,” he added.
“We’ve had so many injuries in the back four that it’s been unfair. Hopefully we have a couple more back against Norwich.”
