Palace secured a place in the FA Cup quarter-finals for the first time in 21 years with a susprise win over Tottenham.

Even more surprising was the match-winner; Martin Kelly grabbed his first ever Eagles goal right on half-time to win it.

But what did we gather from the result? Here's 5 things we learned at White Hart Lane...

1) She wore a yellow ribbon...

Forget the media spiel about the FA Cup losing its magic. This was a roaring, pulsating, invigorating, brilliantly energetic cup tie filled to the brim with action. And Palace persevered.

The FA Cup is still the greatest club competition in football. From its early beginnings in the qualifying rounds - which begins in August - to the latter rounds of the competition, it's a challenge of endurance, of chance and of luck. But it's beautiful and for most football fans unspoilt by the riches of billionaire owners or millionaire squads, it's still a competition you long to win. An FA Cup win would mean the world to us.

2) Kelly took his chance

Martin Kelly probably didn't expect to feature for Palace against Spurs prior to last week's defeat to Watford. Months of being a substitute or unselected must have left their mark on the defender - watching on with frustration as Palace's defence sometimes toiled with the pressure of winless league performances - but you couldn't see it in his display against Spurs.

Against the North London side's strong attacking lineup, Kelly showed composure, tenacity and conviction throughout the match. He offered himself as an option in attack to Zaha, and when the chance fell to him late in the first half, he took it brilliantly.

It's also worth praising Joel Ward for the work he did on the left. Despite being predominantly right footed, Ward did a decent job in the face of endless pressure.

3) Mutch about Balance

Jordon Mutch has found it difficult at Palace. A jack of many trades, he's struggled to master a specific role at the club. Is he a defensive midfielder? A box-to-box player? An attacking mid? A winger? He's played all of these roles for Palace with mixed results and to mixed reactions from the terraces.

It's typical then that, just as Yannick Bolasie finally looks to be nearing fitness again, Mutch seems to have found a position that might work for him - on the wing. Palace have struggled to find the square peg to fill the round void that Bolasie's injury left behind - but in Mutch, there seems to be a modicum of balance to the side again.

Mutch isn't a winger. But his work rate, his flashes of skill and his positional awareness meant that he suited a role that Chung Yong Lee didn't. Against Spurs, he showed intent both defensively and in attack. Is it time for Palace fans to cut him some slack and see what he can do in a more central role?

4) Adebayor and Wickham could work together

There's clearly still a rustiness to Emanuel Adebayor's game. His substitution midway through the second half came at a point where the striker had run himself into the ground. It wasn't a classic performance - he still needs to hone that first touch and get himself to a point where he can last a full 90 minutes and make a more critical contribution - but his experience, and the influence that can have, is showing.

One player that looks to already have gained from this is Connor Wickham. The striker, who like all other Palace attackers has struggled to find the net, put in a performance more befitting of a centre-forward. He was more direct, more willing to take a touch and did all the dirty work, too. There were opportunities in the second half where, with a little more composure, he might have forced a save or even set up a goal -- but he did well to get himself into those positions. Wickham has the ability, but for much of this season he's looked a little timid in attack. Not so yesterday.

It wasn't a typical strike partnership, but the two showed they can play together. With improved service from the wings thanks to Yannick Bolasie's return, we might still see some more goals from our strikers this season.

5) Wilf does the dirty work

For all the talk of Wilfried Zaha carrying our attacking presence on his shoulders for the past month and a half, his defensive game deserves as much credit, too. Against Spurs, in the face of a constant onslaught from Danny Rose and Heung-Min Son, Wilf went beyond the call of duty in providing defensive cover throughout the match.

In a showing of his limitless energy, he would often commit to a tackle then immediately offer himself as an attacking option to pass to. He has made huge strides this season in terms of maturity - the pass to Kelly for the goal was perfectly timed and weighted - and his performances are showing just how capable he is.

Wilf deserves an England call-up. The likelihood is that he won't get one - but with performances like yesterday's - where he showed a willingness to do the dirty work - there will surely be greater pressure on Roy Hodgson to consider him?
