Ronald Koeman came under pressure after losing the El Classico earlier this week. There was a buzz in Spain that the coach will be replaced if he fails to produce against Rayo Vallecano. The rumor came true after failing to win a rather easy La Liga fixture on Wednesday (October 27). Following the defeat, the club stated in an official statement that first-team coach Ronald Koeman has been fired after 14 months in command. Let's take a look at the top candidates for Ronald Koeman's replacement at FC Barcelona.    Ronald Koeman's Potential Successors at FC Barcelona Barcelona's newly elected president Joan Laporta extended Koeman's contract for another season earlier this summer despite his unimpressive style of play. However, he fell short in terms of decision-making. Under his leadership, Barcelona has only 15 points from ten La Liga games this season. His team also lost twice in the ongoing UEFA Champions League group stage. The Barcelona board was increasingly frustrated with Koeman's poor managerial performance, and his termination was on the cards after the defeat against arch-rival Real Madrid. Here are a few prospective Koeman replacements.
