Following a fine spell of form in midfield for the reserves, Dean got the call to head to Priestfield to top up his experience but found himself featuring at right-back for the Championship strugglers. A draw and two defeats later, long-serving player-boss Andy Hessenthaler stepped aside and was replaced for just one game by former Spurs coach John Gorman, who then departed for Wycombe.
Dean also departed at the end of his one-month stint and set about trying to forge a breakthrough at Spurs. This came in some style for the 20-year-old in his first senior start at White Hart Lane - two goals, two assists and an afternoon he will never forget.
"It means everything to me," reflected the Academy product. "Since the day I joined Spurs at nine years old it has been my dream, to make my first start at White Hart Lane. To get on the scoresheet as well is a real dream come true.
"I spoke to Clive Allen and he said it was the chance I've been waiting for. I've had to be quite patient really, Martin has shown a lot of faith in me by putting me in and hopefully I have repaid that.
"I got a phone call saying Brownie was a bit of a doubt and to be prepared. I know Brownie can play through almost anything so I still expected him to be playing, but I am well chuffed to get my chance.
"It was good, a tough game because Everton are doing really well. I thought we made them look pretty ordinary though."
Dean's first strike for the opening goal of the 5-2 win over the high-flying Blues was a result of a well-judged flick by Robbie Keane - ordered by the midfielder!
"I did shout, it probably wasn't the loudest of calls, but it was enough. I just turned, the keeper was racing out and it made it quite easy for me.
"I didn't know what I was doing after that, it was just a dream," he added, going on to admit that he has not scored a better goal than his second.
"I don't think I have, to be honest. I was due a goal, to get two is an added bonus - even though I was pleased just to hit the target."
So, after spells at Swindon, QPR and Gillingham, plus a long wait for his second start following his full debut against Manchester United at Old Trafford last season, was the wait all worthwhile?
"Yes, because the last two loans haven't gone as well as I wanted them to. You can always take something out of anything and it made me more determined.
"Going to different clubs you realise how well you are treated at Spurs and understand more what an opportunity you've got."
Just over a month ago Dean Marney was a frustrated witness to a turbulent period at Gillingham Town. Fast forward and the midfielder was living his dream at White Hart Lane against Everton.
