Gamez was released with only a handful of appearances under his belt at Newcastle. He still hasnt found a new club - though his Twitter bio claims he still plays for the Magpies.

Benitez had zero interest in bringing Slimani back to the club, so instead joined Fenerbahce. It turns out his spell in Turkish was just as bad as his Newcastle one after being told to train with the reserves.
After promising loan spell with Bradford City and Carlisle, Gilliead never did make a first-team appearance for United. He started brightly at Shrewsbury but was in-and-out of the squad in 2019.
Barlaser shone in League One for Accrington Stanley and established himself in their midfield with 39 appearances. He is now being tipped to step up to the Championship this summer.
Aside from the three games missed with a foot injury in October, Saivet starred as a regular for Bursaspor, though he was unable to save them from relegation.
The defender swiftly returned to his homeland with Melbourne City after failing to earn a contract at Blackpool. There is nothing like home comforts to help him recover from a hugely disappointing six years in the North East.
His only Newcastle appearance came in the FA Cup but Findlay has proved to be a hit back in Scotland with Kilmarnock. This week, he has been touted with a move to Sheffield Wednesday.
Injuries prevented Haidara from fulfilling his true potential on Tyneside but it seems the left-back has stayed injury-free in his time with RC Lens, who will compete in the Ligue 2 play-off final on Friday.
Mbemba was frequently left out by Benitez - and it appears the same is happening at Porto. A knee injury delayed his introduction but since regaining fitness in October, he has appeared just eight times - his last coming in January.
Aarons spent the first half of the season at Slovan Liberec before joining Sheffield Wednesday. It started brightly for the winger, but injuries, as they often do, ruled him out of the final seven fixtures.
Toneys name did the rounds on social media in October after netting against Sunderland at the Stadium of Light. It was one of 16 goals for the striker as Posh narrowly missed out on the play-offs.
Gayle does exactly what Gayle does in the Championship - score a hatful of goals. He bagged 24 goals in total - winning the Supporters Player of the Year - as West Brom fell short in the play-offs.
Described at Nottingham Forests most consistent performer with 38 appearances under his belt. Should Benitez remain at St James Park, he will almost certainly be allowed to leave with one year of his contract remaining.
Mitrovic came darting out the blocks at Fulham and left some Newcastle envious of his form. But as the season progressed, his and the Cottagers performances dipped. The Serb ended with a total of 11 goals for the relegated side.
Aside from a groin injury and suspension, Merino played a pivotal and regular part in Real Sociedads midfield with 29 appearances - an upgrade on his 24 at Newcastle last season.
