The young midfielder came in as a late replacement for the injured Michael Brown but had one of those days at the Lane.
In what was his full home debut, Deano scored twice, set up a tap in for Robbie Keane and had a hand in Pedro Mendes' goal in our stunning 5-2 victory.
Head Coach Martin has been impressed for some time with Dean's performances for the reserves.
He said: "I put him in the squad although at first I didn't want to play him because we didn't have any worries, but Jermain Defoe was injured and Michael Brown was injured at the last moment, he tried in the morning but couldn't make it.
"I said on Friday to Dean that he might have to do a job for us.
"I have a lot of faith in Dean Marney, he can score a goal, has a terrific shot from midfield, is always working hard and has a real talent, that is the most important thing.
"I think he's a real Tottenham Hotspur player.
"I'm his coach, I see him on the training ground every day and that is why I have faith in him and why I put him in the team. We had other opportunities on that flank but I had confidence in him and it paid off."
Martin Jol always had faith in Dean Marney - faith repaid in style against Everton on New Year's Day.
