8. Napolioni Nalaga (London Irish)
The Fijian wide-man joined the newly promoted Exiles in 2017, fresh off scoring 22 tries in 32 games during a productive two year spell with Lyon. With the club spending big money, fans were hopeful that his deadly finishing would give them a chance of avoiding the drop. Instead, he looked unthreatening and slow, scoring just one try.
9. Todd Clever (Newcastle Falcons)
After playing professional rugby in New Zealand, South Africa, and Japan over a nearly decade long career Todd Clever will finally get a taste of European rugby after signing with the Falcons in 2015. The 76-cap USA international never really got going at Kingston Park, staying for just one season, making only six appearances.
10. Takashi Kikutani (Saracens)
Fresh from winning player of the year in the Japanese Top League, the experienced international, who had accumulated 66 caps up to that point, arrived at the club from Toyota Verblitz on a training contract in 2013 with the prospect of joining the club permanently.
However, nothing materialised and what started as an exciting transfer move became a complete waste of time.
