Both former manager Marcelo Bielsa and now Jesse Marsch have invested heavily at Elland Road in recent times, with the summer just gone seeing an outlay of £99.13m.
One of their more expensive disappointments could be the deal to bring German defender Robin Koch to Elland Road for £13m.
He had come off the back of a fine season at SC Freiburg, where he featured 34 times in all competitions.
However, since moving to Yorkshire he has been struck down with numerous injuries that have halted his progress. He only managed 17 Premier League games in his debut season, and across his three years has only featured 47 times.
His average SofaScore rating last season of 6.51 is indicative of someone who, when they needed him most, let them down.
He could only win possession 0.2 times per game, as his side kept just one clean sheet in 20 games, and led to LeedsLive reporter Beren Cross describing him as both “horrible to watch” and “not good enough“.
Meanwhile, this campaign, his form has not offered much respite despite a slight improvement, having averaged a 6.62 rating on WhoScored – the ninth-best in the squad currently. Five other defenders have equalled or better his tackle rate at 1.5 per game, too.
These performances combined with his injuries no doubt contributed to the depreciation of his value, which CIES Football Observatory now rate at just €6m (£5.1m).
As this continues to drop, Marsch now faces the daunting task of deciding whether to stick with the underperforming dud and back his ability or try to cash in what is left of him now.
It is clear that the American is likely to choose the former, as he recently came out following his centre-backs omission from the Germany squad: “The only thing I can say is that we’re really happy with Robin. I think everything from his work ethic to his fitness right now to his mentality, he’s grown as a leader.”
He has plenty of growing still to do, but at 26 years old he has time.
It might have to be a swift turnaround, however, as he cannot command his manager’s unrelenting support should he continue with his current performances.
