Some signings absolutely bewilder fans and Aston Villa have acquired a fair number of players that would fall into that category.
Recruitment during the summer transfer window looks to have set Villa up nicely for a Championship promotion tilt this season.
But who are the strangest signings to rock up at Villa Park during transfer season?
Staš is a Villa history boy due to being the only claret and blue player to have scored for the club without ever appearing for them.
The Czech defender scored an own goal whilst playing for Banik Ostrava against Villa in the UEFA Cup but his general showing was enough to convince Dr Jozef Venglos to spend £500,000 to sign him in 1990.
Whilst it is true that Staš was injured in his first training session, the Czech defender did actually make three appearances for Villa in pre-season friendlies.
Despite missing a penalty in the 1-0 defeat to Gornik Zabrze in the pre-season Hanover tournament, he impressed fans and pundits with his performance on the pitch.
However, the closest he came to taking to the pitch at Villa Park was sitting on the bench for the whole of Paul Birch's testimonial game.
Unsworth’s time at the club was completely and utterly bizarre. He decided to leave West Ham for Villa after the two clubs agreed a £4million fee in 1998 having opted for the claret and blues rather than Everton, despite being based in Liverpool.
But after tasting the M6 commute for the first time, Unsworth realised he had made a mistake and told manager at the time John Gregory as much.
Despite Gregory suggesting that he and his wife relocate to Birmingham, Unsworth said his wife was reluctant following the birth of their second child.
Gregory told local press the following about Unsworth’s shock u-turn after agreeing to let him join Everton.
“Apparently it took David three-and-a-half hours to drive home to Merseyside last Friday following his first training session with us.
“It obviously set him thinking, because the poor lad was clearly under the impression that Birmingham was somewhere on the outskirts of Bolton!
“When David eventually arrived home, his dinner was in the dustbin - or perhaps it was in the cat!”
Salifou was the ultimate cult hero among Villa fans. The Togo midfield man was signed by Martin O’Neill in 2007 from Stade Brest and ended up staying at Villa Park for four years.
He never made a Premier League start but did come off the bench four times in his debut season.
‘Sali-Salifou’ echoed around Villa Park regularly on a match day during his stay but he was restricted to just UEFA Cup outings and a single FA Cup start in the remainder of his time at Villa Park with O’Neill resting key personnel for league matches.
Bowery’s arrival on deadline day in 2012 left many fans perplexed. Signed from Chesterfield, Bowery only had 17 goals to his name.
What made Paul Lambert’s decision to sign Bowery even stranger was the fact that Christian Benteke checked in at B6 just a few hours later.
Bowery never actually scored for Villa - in the right end - before being sold. Since leaving Villa in 2014, he’s slipped down the footballing ladder and now finds himself in the lower reaches of League Two with Crewe Alexandra, having joined on loan from Leyton Orient.
Bowery, 25, has scored three times this season to take his career tally to 33 goals in 233 appearances.
Jose Angel Crespo
Poor recruitment was a trend at Villa Park by the time Crespo was signed from Cordoba two summers ago.
A 29-year-old centre-back who had made 52 appearances for six clubs - what could go wrong?
A further two games arrived during his six months with Villa, both of which ended in defeat. He joined Rayo Vallecano on loan in January for the second half of last season and made nine appearances.
Crespo’s Villa career was terminated last summer as he linked up with Greek side PAOK Salonika.
