Tottenham Hotspur reportedly could've signed the Pole for just £100,000 six years ago.
Whether it's Arsenal refusing to pay £100,000 for a Didier Drogba ripping up the French second division, or Chelsea picking up a paltry £15 million for Kevin De Bruyne - who joined Manchster City for nearly four times that amount just 18 months later - Premier League clubs occasionally get it horribly wrong. Might Spurs be about to follow suit?
According to Spanish outlet Estadio Deportivo, Liverpool and Everton are battling to sign £10 million-rated Ajax striker Arkadiusz Milik - the 22-year-old who Tottenham reportedly passed on for £100,000 following a trial with the club six years ago.
The Mirror reported in November that Milik - who finished the Eredivisie season with 21 goals from 28 starts - had a trial with the Lilywhites as a 16-year-old, only for the club to pass up the opportunity because they had 'better players of his age on their books'.
Harry Redknapp would have been the manager at the time but the report does not state who made the decision to let him go. After that, the Poland international went on to join Gornik Zabrze for 500,000 Zlotys - now the equivalent of £90,000 GBP.
He is set to feature heavily for his nation at Euro 2016, having starred alongside Robert Lewandowski in helping the Poles secure automatic qualification, netting six times in the process.
Tottenham might be hoping that Milik does not join a Premier League club this summer in fear of him hitting the ground running, further exposing their reported decision not to sign him.
Arsenal and Chelsea will be haunted by their aforementioned errors in judgement for a while yet.
