4) Joelinton (Hoffenheim to Newcastle – £40m)
Another club-record buy that has failed to live up to expectations, with the Brazilian having scored just six Premier League goals during his two campaigns with the Magpies.
Although not an out-and-out striker, Joelinton’s goal return is extremely poor and, while he can still improve at 24 years of age, Newcastle are very unlikely to get their money back.
