As part of our end of decade series looking back at the last 10 years of Newcastle United, it is time look at the men who arrived on Tyneside but failed to live up to expectation.
Since 2010 United have had their fair share of signings who came into the side with hope of becoming the next hero in black and white but left St James' Park producing anything but their best.
From exciting and expensive signings where perhaps injury got the better of them to the openly uninspiring arrivals - this is the list of the biggest Newcastle United flops of the last 10 years.
Emmanuel Riviere - 2014-17
Proof that Graham Carr could get it very, very wrong.
In Riviere's defence, the striker was brought in with the intention of being a second striker where there would be time to develop, but quickly found himself thrown in at the deep end.
Right from the off it didn't look anywhere near a good fit. A poor touch, a lack of pace and inability to hit the target meant it wasn't long before fans were questioning just why he was bought.
A pricetag of £6million wasn't the heaviest outlay but on a good pay packet, 28 appearances and just three goals meant United got little value for the move.
Sol Campell - 2010-11
His better days were long behind him, and yet Chris Hughton pushed to bring the then 35-year-old to St James' Park.
Signing a one-year-contract, it's often said to be the deal which burnt owner Mike Ashley's fingers the most.
Hughton obviously wanted to tap into Campbell's experience but the defender turned out just seven times for United.
Seydou Doumbia - 2016
Newcastle needed goals and it was Seydou Doumbia who arrived on loan from Roma with a good goalscoring record.
But he hadn't played for two months due to the winter break in Russia - he had previously been on loan at CSKA Moscow - and he struggled to regain match fitness.
In a recent exclusive with Chronicle Live - Doumbia claims the sacking of Steve McClaren cost him a chance to prove his worth at Newcastle after he made just one appearance under Rafa Benitez.
Siem de Jong - 2014-17
One of the biggest frustrations of the last decade. The four-time Dutch champion arrived at Newcastle for what should have been a bargain £6m.
He had been linked to United many times over the years and there was a genuine buzz when he arrived. A playmaker with a great eye for a goal, and even better ability to pick a pass.
But injuries cost him. Within a few weeks of arriving a thigh injury ruled him out for several months and that was the start of a nightmare on Tyneside for him.
A collapsed lung followed, before a freak eye accident followed.
Made just 22 appearances in three years at St James' Park.

Remy Cabella - 2014-16
United paid Montpellier £8m for the forward, and almost instantly regretted it.
The talent was there but he struggled to adapt to the Premier League - lasting just one season before being shipped back to Ligue 1.
There were glimpses of what he could do - he won player of the month in January 2015 but ultimately he couldn't maintain that form.
Here's the big list of long reads with former Newcastle United players - who have spoken exclusively to Chronicle Live.
Florian Thauvin - 2015-17
There were question marks over how much the Frenchman wanted to make the move ahead of his £15m switch from Marseille.
Stronger than Cabella, he certainly had more chance of making it in the Premier League but never really settled.
Again, there were glimpses but headed back to Ligue 1 on loan after just five months.
After moving back to Marseille he's excelled - and won the World Cup with France.
Chancel Mbemba - 2015-18
Arrived for £8m after winning the Belgian title with Anderlecht, but suffered from being unable to speak the language. He dropped down the pecking order after Rafa Benitez took over from Steve McClaren and, prone to odd lapse in concentration, struggled to break back into the team.
One of those fans will wonder 'what if' about - Mbemba left for FC Porto after just 54 games.
Mapou Yanga-Mbiwa - 2013-14
Another frustrating buy - especially after the centre-back came with the pedigree of captaining Montpellier to the Ligue 1 title.
Bought as part of a January spending free to stave of relegation in January 2013, then manager Alan Pardew often played the four-timed capped French international out of position.
He made 37 appearances before being loaned out to AS Roma.
Sylvain Marveaux - 2011-14
Marveaux's arrival raised a few eyebrows, with the Frenchman previous linked to a move to Liverpool.
Injuries sadly got the better of him however, as the winger ruled out for several months in November 2011 with a hip injury and United fans never got to see the best of him.
His best run of games came as part of Pardew's team which made it to the quarter-finals of the Europa League but, like many of the Ligue 1 imports around that time, it was very much a case of unfulfilled potential.
Matz Sels - 2016-18
The goalkeeper was Rafa Benitez's first signing as the Spaniard looked to build a squad capable of returning to the Premier League.
Costing £6.5m, Sels' initial introduction to English football was solid enough as he kept four clean sheets in the opening weeks of the season. But a poor performance against Aston Villa saw him replaced by Karl Darlow - and didn't even make double-figure appearances for the club.
