FIFA have rejected Leicester City's attempts to overturn their decision to block the Portugal international's registration. Leicester were unable to register Silva, who they attempted to sign from Sporting CP on the final day of the transfer window, because they missed the deadline by 14 seconds. Here are five players that Leicester City need to stand and be counted before Silva can be registered and play a role at the start of 2018. Since his move from Genk in January 2017 the Nigerian...
Since his move from Genk in January 2017 the Nigerian midfielder has been a regular starter for the Foxes.
Seen as the man to fill the void left behind by N'Golo Kante, Ndidi has largely been impressive since his £17m transfer. His defensive work rate has seen him rack up a high number of tackles and interceptions, whilst he has also contributed going forwards with stunning goals against Derby County and Stoke City.
However, Ndid is still learning and doesn't have the ability to control the midfield yet. His partnership with Drinkwater last season was helpful in this development, but now with Drinkwater moving to Chelsea he needs someone else to step up alongside him.
Iborra's Leicester career has got off to a slow start after the midfielder picked up a groin injury during pre-season.
The Spanish midfielder made his return in Leicester's recent EFL Cup win over Liverpool, and came on as a sub in the 0-0 draw with Bournemouth.
The former Seville captain comes with impressive credentials having won three Europe Leagues with the club. If Leicester can get him up to speed, then he could be the man to fill the void created by FIFA's rejection of Silva.
Matty James's return to the Leicester City side is a feel good story. The Manchester United academy graduate suffered a horrific injury against Southampton in 2015 rupturing his anterior ligaments. He ended up missing the entirety of the following campaign, in which Leicester were crowned Premier League champions.
The midfielder spent the latter half of last season on loan at Barnsley in order to prove his fitness, and after impressing for the Yorkshire club found himself starting Leicester's first few Premier League games this season.
He is currently out injured with an Achilles problem, but the midfielder will be looking to fight for his starting place upon his return.
It's been 10 years since Andy King made his debut for Leicester City, and since then the Wales midfielder has made over 350 appearances for the foxes winning the League One, Championship, and Premier League with the club.
This achievement makes him the first player to win the top three divisions with the same team in the Premier League era. He is also Leicester's all-time highest-scoring midfielder and all-time most capped international. At international level, he was part of the Wales team that reached the semi-finals of UEFA Euro 2016.
Despite all this, it's been a number of seasons since King could consider himself as a regular starter at the King Power. The recent injury to James has given him an opportunity to start the last few games, and King really needs to make the most of this chance if he wants to keep his place in the starting XI.
Daniel Amartey has largely suffered due to his versatility. The Ghanaian international has not been allowed to develop in one position since his move to Leicester.
Last season Amartey was initially considered to be the natural replacement to N'Golo Kante and was a regular in midfield before he was called up to AFCON in January. Upon his return to Leicester, he found himself replaced by Wilfred N'didi and first team opportunities limited.
It seems like Amartey might be better suited to a role in defencee, and his performances at the AFCON 2017 saw him named in the CAF Team of the tournament as a centre back. However, he could also now be presented with the chance to fight for a place in the Leicester midfield and regular first team football.
