Ronald Koeman. [Photo/Agencies] Ronald Koeman said on Tuesday he needs more time to instill his ideas after his poor start as Barcelona coach. The pressure is already mounting on Koeman, whose future could become more uncertain when the club's new president is voted in later this month. Asked when his methods will deliver better performances, Koeman said: "Little by little we are going to see it. We have tried to take the team forward and to prepare them for the championship but we have important players out injured and I have a squad I have not been able to change much. I need more time to impose my ideas." Barca is fifth in La Liga, 10 points off leader Atletico Madrid. Unsettled superstar Lionel Messi has said he will decide on his future with the Catalan club in the summer.
