Leicester City are poised to sign Belgium midfielder Youri Tielemans on loan from Monaco in what could transpire to be one of the most significant deadline day moves.
The deal will see Portugal midfielder Adrien Silva move in the opposite direction to the struggling Ligue 1 club.
As a teenager, Tielemans was almost universally regarded as one of the most exciting up-and-coming talents in the European game.
But the midfielder has lost his way since leaving Anderlecht, the club who nurtured him, for Monaco at the end of the 2016-2017 campaign.
Indeed, at the age of 21, Tielemans finds himself being effectively forced out of Monaco by returning manager Leonardo Jardim.
The pair did not really see eye-to-eye during Jardim's first spell in charge of the principality club with Tielemans struggling to perform during his first season.
Tielemans was much closer to Thierry Henry, but his abysmal record of just four wins in 20 matches in charge, which sees Monaco second bottom in Ligue 1, meant he wasn't going to last too much longer.
Now that Jardim has returned, Tielemans is on his way to the Premier League and has the chance to reinvigorate what is still a hugely promising career.
Despite Monaco's many problems this season, Tielemans has still emerged with plenty of credit. He has scored five goals in the league, a solid return for a central midfielder in an underperforming side.
Considering he managed only the one goal during his debut season at Monaco, it shows that Henry helped to coax out this aspect of his game.
But the attribute that could really help Leicester, considering their preference to play on the counter-attack, is Tielemans' willingness to make surging runs from deep.
It certainly offers an alternative to Leicester's wing play and high balls in search of Jamie Vardy and that could well prove invaluable.
Tielemans is also unafraid to put in a challenge, something he'll no doubt be required to do more of in the physically unforgiving Premier League, while he has in the past demonstrated an ability to control the midfield tempo.
Indeed, it was as a holding midfielder that Anderlecht first deployed him as a teenager making an impressive breakthrough in Belgian football.
But as he worked on the more attacking elements to his game, he was pushed forward into more of a No 10 position, the same as he played in Anderlecht's youth teams.
Really, the club might have known. Tielemans, who was born nearby in Sint-Pieters-Leeuw, had been with them since the age of five and worked his way through all of their youth ranks.
There had been plenty of excited whispers about his potential before he made his first-team debut against Lokeren on July 28, 2013 - just two months after his 16th birthday.
And it said everything about Anderlecht's faith in the teenager that he made his Champions League debut in October 2013 aged just 16 years and 148 days - the third youngest debutant in the competition's history.
Tielemans has drawn comparisons with box-to-box midfielders such as Frank Lampard, while the head of Anderlecht's youth department Jean Kindermans saw him as more like compatriot Axel Witsel.
He quickly established himself as a regular in the Anderlecht midfield, racking up 185 appearances and 35 goals for the club all before the age of 20.
In that time, he helped them to league titles in 2014 and 2017, the latter coinciding with a run to the quarter-finals of the UEFA Europa League, when they were a little unfortunate to lose to eventual winners Manchester United.
Inevitably, Tielemans was soon being linked with the European elite but his desire to continue getting regular game time rather than just sitting on the bench was behind his decision to join Monaco for around £20m in May 2017.
Unfortunately, things didn't start out too well, with Tielemans named by France Football magazine as one of the league's biggest flops during the first half of the season.
His patchy form didn't prevent a call-up to the Belgian squad that reached the semi-finals of the World Cup last year though Tielemans was only started by Roberto Martinez in the group dead rubber with England and the third place play-off against the same opponents.
Now Tielemans will hope a move to England will provide his career with fresh impetus as we wait for his enormous potential to be realised on the biggest stage.
