The midfielder finally looks clear of his injury problems after managing only 15 appearances between September 2003 and September 2004.
He sat it out for four months with a hip injury during which he missed Wales Euro 2004 play-offs - they lost to Russia - and on his recovery, managed only nine appearances before another setback, this time a shin problem that kept him out for a further two months.
Those shin problems eventually required surgery in pre-season before he finally returned against Norwich City on September 12.
He's made 13 appearances since then but found himself on the bench in our games against Burnley and Arsenal last week.
"I haven't hit it off yet but you can't just walk back into the team and continue where you left off after the year I had," reflected Simon at Spurs Lodge this week.
"The game is hard work for me at the moment. It's hard to get to that peak fitness you need.
"I haven't had a full pre-season like the rest of the lads and it shows, even in training, I'm looking around and the boys are looking sharp and I'm breathing a bit heavier.
"It's one of those things. I've been fit for a long time now and I have to sustain it and when I get another chance I'll be alright."
With that in mind, Simon says he's not surprised he's found himself on the bench.
"The standards we're looking to set if you aren't doing well, you won't keep your place," he added. "That's the way it is.
"I know what I think I can achieve and I'm trying my hardest to achieve it.
"All I can do is keep my head down, work hard and wait for another chance. That's what football is about."
Simon Davies admits he's struggled to reach his own high standards again after a year on and off the treatment table.
