According to reports, West Ham and Sunderland had hoped to sign Italian striker Ciro Immobile in 2016.
Hammers boss Slaven Bilic had been hoping to secure the signature of Immobile after he lost out on signing Christian Benteke.
It looks like the East London club made a massive mistake by not following up on their interest as Immobile has since matured into one of the most lethal strikers in Europe.
He has so far scored 13 goals in eight starts across all competitions for Lazio this season. The Hammers struggled during the second half of last season after they lost Dimitri Payet and perhaps if Immobile was in their side, they would have fared better.
In addition to being linked with the Hammers, Immobile was also linked with a January move to Sunderland who had then been managed by Sam Allardyce.
In the end, Allardyce decided against following up on a move and stuck with Jermain Defoe, Dame N’ Doye and Fabio Borini.
