When Tottenham paid £10m for Jack Clarke in the summer of 2019, it's fair to share that plenty of eyebrows were raised.
Clarke had started just four Championship outings for Leeds in the season prior and in the process, had only found the back of the net on two occasions.
It was a breakthrough season from the teenager but to say he was worth an eight-figure fee would be pushing it.
Indeed, in his career since, he has proven that he wasn't worth that sum of money at all. It's hardly surprising, but not many would have predicted his career to have fallen away quite as it has.
Following the 2018/19 season, it looked as though Clarke was ready to push for a regular starting spot at Leeds, but his move to north London has arguably been the worst possible thing for him.
He was loaned back to the Whites for what was supposed to be the duration of the 2019/20 campaign but he returned to Tottenham in January having featured just once in the second-tier.
Marcelo Bielsa wasn't impressed with his performances or attitude and as a result, he couldn't find a way into the team.
Clarke was forced to play in the U23s and his frustration was clear. After being substituted against Stoke U23s, he refused to shake the hand of the player that was replacing him, something that just about summed up the 19-year-old's slippery decline.
He is not the player he showed 18 months ago and despite featuring on the bench in Spurs' Europa League matches this term, has still only played for Jose Mourinho's side on a solitary occasion.
But what does this all have to do with Leeds in the present day? Well, a player they signed in the summer is following in a similar path.
Although it would be a bit strong to suggest that he's definitely going to become another Clarke, Crysencio Summerville has certainly endured a frustrating start to his life at Elland Road.
The Dutch youth prospect was signed in the summer for a fee in the region of £1m but we're yet to see him on the first-team stage.
Furthermore, the teenager has played just twice in Premier League 2 for Leeds U23s.
This all comes after a season where he contributed to five goals in the top-tier of Dutch football - the Eredivisie.
Thus, like Clarke, Summerville has taken a step back. He's gone from playing senior football to having to settle for a place in the reserves, failing to develop much as a consequence.
One outlet in the Netherlands, De Telegraaf (via Sport Witness), recognised this fact rather strongly this week.
They wrote: "For Summerville there were opportunities as a winger, all the more because Feyenoord was not well occupied on the wings. But Summerville preferred to play for a Leeds United youth team. There he has not even played in the first team for a minute."
It's a brutal assessment but at the same time, it speaks volumes about how highly he's thought of.
When Leeds first signed Summerville, he was noted for his ability to "cause nightmares" for defences. They were the words of journalist Jonty Colman who profiled the youngster earlier this year.
When a first-team opportunity beckons for the attacker remains to be seen. After all, Bielsa rarely changes his team. Clarke knows that all too well.
The early signs don't bode well for the talented flanker.
