Former Arsenal head of recruitment Sven Mislintat was stunned by Gunners' manager Unai Emery's decision to bring Barcelona midfielder Denis Suarez to the Emirates stadium.
Emery was determined to sign the Spain international, despite Mislintat's deep concerns over the player's abilities.
Suarez endured a miserable spell in England, failing to adapt to the physicality of the English game and suffering a string of injuries, leaving the Spaniard with only four Premier League appearances to show for after spending six months in London.
The loan deal was eventually cut short due to his injury problems, and Suarez returned to Spain, where he signed a permanent deal with La Liga side Celta Vigo at the end of the season.
