Losing Robin van Persie to Manchester United in the summer of 2012 was nothing short of embarrassing for Arsenal and their fans.

Although handsomely compensated with £24m for an injury-prone, 29-year-old with one year left on his contract, the symbolic nature of the Dutchman's pining for a bigger club hurt everyone with a stake in Arsenal.

Arsene Wenger's hands were tied. The club - yet to renegotiate key sponsorship deals - couldn't risk missing out on the large sum of money by keeping an unhappy player for another year.

The suffering didn't end there.

Arsenal stood by whilst Manchester United - helped greatly by Van Persie - romped to the title, whilst the Gunners limped in to the last Champions League place. Times were tough for a set of fans used to being top dog, or at least on a level playing field with the Old Trafford outfit.

But a summer of change has threatened to reinvigorate Arsenal's fortunes.

Manchester United have lost their inspirational leader, Sir Alex Ferguson, to retirement, whilst Arsene Wenger dusted off his chequebook and turned on the charm to convince Mesut Ozil - one of the world's brightest talents - to move to the Emirates in the summer.

United are struggling in the early days of the Premier League season whilst Arsenal are flourishing. It looks as though the tables are finally turning around. A shift of power is occurring.

But Arsenal can't sit back. They must drive the stake in to United while they're down. Nothing will do that more than the acquisition of former United starlet Paul Pogba.

Pogba defied Ferguson by quitting Old Trafford to join Juventus. He has since flourished in Turin.

But the Serie A champions sound like they are tempted to cash in on the 20-year-old star, admitting a big bid would be hard to refuse. £40m is believed to be enough to ensure his release.

Despite being well stocked in the area, Arsenal must sign the player to underline their new-found dominance over the old enemy and underline the idea that they can once again compete with the big boys.

Not only would they be getting one of the brightest young talents in world football but it would be the ultimate payback for United's capture of Robin van Persie.

Yes, United would still have a fine goalscorer on their books, but he is ageing and getting greyer by the day. Arguably, he is one bad injury away from losing that golden touch. 

Pogba on the other hand looks set for a career at the top and will only get better.

At Arsenal he could be a constant thorn in their side - a reminder of when the tides turned and Arsenal took the crown of the champions, possibly for good.
