This season has seen a shift of power in north London.

For so many years Arsenal have had the bragging rights over their neighbours Tottenham but it looks as though that is all about to change.

In a season that has seen the Gunners flatter to deceive once again, top of the Premier League at the start of 2016 before falling apart in another meltdown, Spurs look set to put the final nail in their bitter rival's 2015/16 coffin, as they are on course to finally finish above the side from the Emirates.

The men from White Hart Lane have come on leaps and bounds this year under Mauricio Pochettino and were the only team for a long period that looked like they could stop Leicester City's surge to this year's title. That did not come to pass, but there's a big air of optimism over at N17 ahead of next year, which is far more than can be said at Arsenal.

But why has this come about? How are Tottenham now better than Arsenal? FootballFanCast takes a look...

World Class Striker

Harry Kane celebrates

Harry Kane has proven himself to be the real deal this season. After notching 21 goals last campaign the Spurs frontman has extinguished any thoughts that he would be a one hit wonder with another 25 this year.

He's quickly becoming the complete forward, he can head, use either foot, score inside and outside the box and as this year's top scorer in the league, he has highlighted his truly world class ability.

He'll be leading the line for England at Euro 2016 and it's testament to his talent that he's made that position his own. Now compare this to Arsenal's main forward - Olivier Giroud.

Make no mistake, Giroud is a decent player on his day but is he world class? No chance. Giroud has 12 goals to his name this year and with players around him like Alexis Sanchez and Mesut Ozil, he should be scoring a lot more.

Arsene Wenger needs a world class forward still and the mind boggles as to why he hasn't got one yet.

Mauricio Pochettino's stock has risen incredibly this year.

When he joined Spurs in 2014 he'd taken over a club still trying to replace Gareth Bale, with a clutch of signings that never looked like they were going to gel. The turnaround has been amazing.

Spurs have been moulded into one of the league's most cohesive units and they follow the Argentine's instructions with aplomb. You cannot overestimate the job 'Poch' has done at Spurs in just two years and the future looks bright for the Lilywhites.

Arsene Wenger, on the other hand, looks out of touch. Ten years ago Wenger was easily one of the best managers around, he was celebrating a decade as the Gunners boss in which he had seen league and cup doubles, a run to the Champions League final and, of course, the Invincibles season.

The Frenchman's style of play was a breath of fresh air in the Premier League as his swashbuckling Arsenal sides were one of the most formidable in the country, but since then it looks like he's run out of ideas.

Football, and the way to play it, changes all the time and while the most successful managers adapt to continue at the top level, Wenger seems stuck in his ways. He's lost that aura about him, an aura that seems to be growing around Pochettino instead.

Improving young players

Spurs have the youngest average aged squad in the league. This can only mean the team are going to improve over the years and equally, given their lofty standings this season, Tottenham's youngsters are clearly a hugely talented bunch.

Harry Kane and Dele Alli at 22 and 20-years-old respectively have at least another 10 years at the highest level, which Spurs fans will hope is with their team. Then when you consider the fact key players like Christian Eriksen, Eric Dier and Danny Rose are all under 25 and have had their best seasons to date, Tottenham are going only one way; up.

Arsenal have also got a batch of promising young players but they seem to have stalled in their development. Jack Wilshere, although plagued by injuries, hasn't helped himself with off field misdemeanours. Alex Oxlade-Chamberlain hasn't shown that great form from when he first signed and Aaron Ramsey seems to have lost his way slightly to0.

Arsenal have got good young players but seem to lack any intensity compared to their Spurs counter parts at the moment, but where the blame lies for this is up for debate.

Case for the defence

Toby Alderweireld (2)

Spurs have the best goal difference in the league and that is largely thanks to their defence.

Spurs have conceded fewer goals than anyone else this season and have a back four that all know what they're doing. Danny Rose has become England's finest left-back and Kyle Walker's defensive attributes have also improved.

Meanwhile, the centre-back pairing of Toby Alderweireld and Jan Vertonghen has been hugely influential in Tottenham's rise - and in Alderweireld Spurs arguably have the best centre half in the Premier League right now.

Finally, Hugo Lloris is one of the world's best goalkeepers, and would walk into pretty much any side in the world.

Arsenal's defence is by no means dreadful, but it lacks the organisation of Spurs'. 17 clean sheets, the most in the league this year, shows how good a signing Petr Cech has been but it's the four in front of the Czech that have let him down.

Hector Bellerin has had a good season and Laurent Koscielny looks great at times, but there's always a mistake in Arsenal's back four if you put them under pressure. West Ham showed a few weeks ago that they're still not great with aerial threats and you look at that back four and think, who's the organiser? Who's the one that gets the rest of the back four in position?

There isn't an obvious answer and that's what has let Arsenal down.

Fan Harmony

The amount of discord flying about at the Emirates between fans is clearly hampering the team's performance. Wenger seems to be facing more and more protests as the weeks go by and the division between his accusers and disciples is only getting bigger and bigger.

It's a rather toxic atmosphere at Arsenal and until that gets resolved, results on the pitch are going to remain as they have been recently, uninspiring.

Things at White Hart Lane could not be more different. You'd be hard pressed to find a Spurs fan unhappy with the way the team has carried on this season, nor would you find a Pochettino detractor.

Everyone at Spurs seems to be pulling the same way and the fans have played a big part in Spurs' title push this year.
