The 39-year-old converted from the penalty spot in some style in extra time to see off Watford 1-0 at Wembley and send Crystal Palace back to the Premier League and an estimated £120million windfall.
Phillips moved to Selhurst Park on loan from Blackpool in January but the evergreen frontman now finds himself out of contract and not quite ready to hang up his boots, despite previously announcing his intention to retire this summer.
If he were to be offered and then accept terms to remain with the Premier League new boys then it would make Phillips, who turns 40 at the end of July, the oldest outfield player currently in England's top division by four months, ahead of Manchester United stalwart Giggs.
And it could potentially put him within sight of Teddy Sheringham's record of Premier League involvement at the age of 40 years and 272 days.
"Whether it's my last game or not, I doubt it will be, but it's probably my last chance at Wembley," said Phillips after yesterday's momentous victory.
"I'm pretty much sure I will carry on in some capacity. Where? I don't know.
"I'm just going to go on holiday now and relax. I don't want to be making a decision in the next couple of days that I'll regret.
"We'll see what happens, I've had a couple of offers already but I haven't said yes or no."
