#1 Dmytro Chygrynskiy

Dmitro who? was the expression of many Barcelona fans when Pep Guardiola sanctioned the purchase of the then 23-year-old from Shakhtar Donetsk for €25 million.
The Ukrainian had excelled in his homeland for Shakhtar, guiding the club to triumph in the 2009 Europa League and Guardiola was said to have been impressed with his displays in the 2009 UEFA Super Cup against Barcelona.
However, not much was known about him outside his homeland, but Pep's spectacular achievements in his first season as Barca coach meant that he was largely given a free hand to do what he pleased.
He was the first ever Ukrainian to represent Barcelona and it was expected that Chygrynskiy would be the long term successor to Carles Puyol and would further strengthen the Blaugrana backline with his 'aerial presence and strong defensive skills'.
As it happened, neither of those came to fruition, as he struggled to break into the Barcelona starting lineup making just 14 appearances in all competitions in his sole season at the club before being sold back to Shakhtar for €15m just a season later.
He departed Nou Camp without making an impact and his lasting legacy would be of having an incredibly long and difficult last name to pronounce, while he is also destined to make it into all-time lists of worst and most shocking transfers in the great club's illustrious 119-year history.
