Southampton's decision to sign Guido Carrillo in January 2018 will undoubtedly go down as one of the worst transfers in the club's history after he was allowed to leave on a free transfer last summer.
The South Coast club were keen to reinvest following Virgil van Dijk's £75 million move to Liverpool and ended up significantly overpaying for Carrillo as a result, with the Argentine joining in a £19 million deal from AS Monaco.
Les Reed, who was the Southampton vice-chairman at the time, said this about Carrillo's signing:
"Guido represents a very exciting addition to our attacking options ahead of the final months of the season.
"We are confident he will benefit us not only in the remainder of this campaign, but in the years to come."
Unfortunately for Reed and Southampton, this would not prove to be the case.
The 29-year-old striker would make 10 appearances in the remainder of the 2018/18 season, scoring no goals and providing just two assists before never being seen in a Saints shirt again.
He would subsequently spend two seasons on loan with CD Leganes in La Liga, where he would manage just 10 goals and three assists in 60 appearances for the club, with his market value seriously declining during his time in Spain.
As a result of his poor performances, Southampton made the decision to terminate his contract last summer so that he could join Elche on a free transfer, bringing an end to a nightmare spell on the South Coast.
Although you could argue that Carrillo was never really given an opportunity to impress at Southampton, Ralph Hasenhuttl clearly didn't feel he had shown enough to deserve a chance in his side, which really makes you question why he was brought in for as much as £19 million in 2018.
Therefore, Southampton's decision to sign him clearly proved to be a huge error and the fact that his contract was terminated emphasises that as they were clearly very desperate to be rid of him last summer.
And, in other news... Semmens must not be bullied when selling £20m Saints beast this summer
