Newcastle United have been slammed by TalkSport's Simon Jordan, who has claimed the Tyneside club are not on the same level commercially as some of their Premier League rivals.

What's the latest on Newcastle's commercial deals under PIF?

The Magpies are currently sponsored by a United Kingdom-based company that will no longer feature on the front of the club's shirt from next season.

It is believed the Magpies will now be looking to land a much larger deal with another company ahead of next season as the club look to work their way around the FFP limitations.

During the January transfer window, those within the club made it very clear their hands were tied over how much they could spend during the month because of FFP.

And speaking on TalkSport, Jordan has slammed the Toon as being nowhere near the same level as the other sides in the 'big six' of the Premier League:

"Newcastle have got 20 years to catch up with the brands of Chelsea and Manchester City, and Liverpool and Arsenal in the Premier League.

"Right now, Newcastle are doing very well in the league, but as a commercial operation, with global eyes on the prize, they ain't anywhere near the ideals behind Chelsea and Man City and Liverpool and Arsenal and Spurs and Manchester United.

"You are a big club in Newcastle. You're not a big club on the world stage. You will be."

What would new sponsors mean for Newcastle?

It is apparent the Newcastle owners are looking to grow the club off the pitch as well as on it with the club having already landed a Saudi Arabia-based sleeve sponsor since PIF's arrival.

It is believed the current deal Newcastle are in with their shirt sponsors is bringing in around £6.5m to the Tyneside club per season.

And this shows the huge gap between the likes of Manchester City who are reportedly bringing in a revenue stream in the region of 10x that figure.

When reports are now suggesting Newcastle's sleeve sponsor is bringing in more than their main sponsor, this shows where the issues lie.

However, in terms of Jordan's comments, Newcastle do not currently seem to have the worldwide following that some of their rivals do.

Although followers on social media do not determine the size of a Premier League club, it is something which will carry value with potential interested sponsors.

For instance, Manchester United have in the region of 35m followers on Twitter in comparison to the 2.4m that Newcastle have.

So there is certainly some substance to what Jordan is saying, however, it will be interesting to see whether Newcastle's owners look to source a Saudi-based sponsor which could prove to be incredibly lucrative for the Toon.

And this could follow similar steps to what Manchester City have done with the backing of the United Arab Emirates-based company Etihad Airways.
