Weeks after breaking the world transfer record to bring in Paul Pogba, Manchester United and their City rivals look set to smash it again.

Reports are emerging claiming the Red Devils - who paid £89m to get Pogba back from Juventus - and Manchester City are looking to activate the £170m release clause in Neymar's contract to bring him in, with a move to Manchester a real possibility.

There is no guarantee Neymar would go along with any move, after PSG's lucrative offer was snubbed by the 24-year-old so he could continue to play with fellow South Americans Lionel Messi and Luis Suarez.

But the idea Neymar may one day wish to move on to leave Messi's shadow has always followed him around.

A lot of fans would baulk at such an astronomical fee, but it can be argued that the Brazilian is one of few players in the world who could actually be worth it, particularly in the current market.

Here are three reasons we think Neymar would be worth a record £170m transfer fee...

HE IS PART OF THE GREATEST ATTACK IN THE WORLD

The Messi-Suarez-Neymar axis - so successful it is merely now known as 'MSN'- is the most deadly strike force right now and possibly of all time.

The trio managed a staggering 253 goals between them in the 2014/15 and 2015/16 seasons combined - a figure made only more impressive by the fact that Suarez missed the first few months of the 2014/15 season through suspension.

While there is an almost telepathic relationship between the three South Americans, all are incredible players in their own right and would likely tear the Premier League apart. You only need to look at Suarez's last campaign for Liverpool - where he managed 31 goals and 12 assists in 33 games - as proof of that.

HE IS ONLY 24

Having seemingly been at the top of the world game for so long, it is easy to forget that Neymar is only 24 years of age.

Before he even joined Barcelona at 21, the Brazilian had well over 100 professional goals under his belt and was drawing comparisons with the legendary Pele.

He also became captain for Brazil at the 2015 Copa America and led Brazil to glory in Rio at the 2016 Olympics. While it's a large sum of money, £170m may well prove worth it for a man who has won so much yet still has plenty of years left in him.

WE HAVEN'T SEEN THE BEST OF HIM

The scary thing is, Neymar probably hasn't even hit his peak yet.

As pointed out above, the Brazilian is only 24 and probably has another five or six seasons before his peak.

We are also arguably yet to see him at his best as a result of being in the same team as Messi.

Neymar's best form in a Barcelona shirt has largely come when the Argentine has been out of the side, while many predict Neymar will take his crown as the world's best player when Messi finally steps aside. The question is, will he do so in a Barcelona shirt, or in another team's colours?
